You gotta love it when science cannot currently explain how some repeatable experiment occurs. Always a good opportunity for a paradigm shift.

>1990s in a class of materials called perovskite manganites

Isn't that the stuff used in solar panels also? Does this have application in solar too?


Similar-Afternoon567 t1_jaceh9k wrote

Perovskite refers to the arrangement of the atoms within the crystal structure. There are lots of different perovskites with a widely divergent chemical compositions and physical properties.


RecognitionOwn4214 t1_jacctow wrote

Perovskite solar cells already exist, but come with some disadvantages as it's brittle.


Goliatheos OP t1_jae9b1l wrote

Perovskite manganites are a type of material that has been studied for their potential use in solar cells, but they are not currently used in commercial solar panels. They are typically made using silicon.

>alignment of the spins of the electrons in the material

The alignment of spins of electrons is an important factor in determining the electrical properties of a material. In general, materials with unpaired electrons and partially filled d or f electron shells tend to have strong magnetic properties and are more likely to exhibit spin alignment.

Ferromagnetic materials, such as iron, cobalt, and nickel, have strong spin alignment and are ideal for improving electron flow in electronic devices such as hard drives, transformers, and generators. In these materials, the unpaired electrons are aligned in the same direction, which results in a net magnetic moment and a strong attraction between neighboring atoms. This alignment of spins creates a pathway for electrons to flow more easily through the material, making it more conductive.

Other materials that can exhibit spin alignment and improve electron flow include ferrimagnetic materials (such as ferrites), antiferromagnetic materials, and certain types of semiconductors (such as diluted magnetic semiconductors).


Goliatheos OP t1_jaea4va wrote

Several examples of elements and molecules that have been studied for their spin alignment properties in the presence of a strong electromagnetic field to optimize electron flow are graphene, a two-dimensional sheet of carbon atoms arranged in a hexagonal lattice. Graphene has unique electronic properties due to its high surface area, high electron mobility, and the ability to form spin-polarized states under certain conditions.

Another example is nitrogen-vacancy (NV) centers in diamond. NV centers consist of a substitutional nitrogen atom adjacent to a lattice vacancy in a diamond crystal. They exhibit long-lived spin states that can be manipulated by applying a magnetic field or microwave radiation, making them promising candidates for applications in quantum computing and sensing.

Additionally, organic molecules like porphyrins and phthalocyanines have been studied for their spin alignment properties.

Besides iron, cobalt, and nickel, there are several other elements that can exhibit strong spin alignment and be useful for improving electron flow in electronic devices. Some examples include:

Neodymium (Nd): This rare earth element has strong magnetic properties and is commonly used in high-performance magnets, such as those used in computer hard drives.

Samarium (Sm): Another rare earth element with strong magnetic properties, samarium is often used in high-strength magnets and magnetic storage media.

Dysprosium (Dy): This rare earth element has very high magnetic strength and is often used in high-performance magnets for applications such as electric motors and wind turbines.

Gadolinium (Gd): This rare earth element is often used in magnetic refrigeration systems and as a contrast agent in magnetic resonance imaging (MRI) due to its strong magnetic properties.

Platinum (Pt): While not as strongly magnetic as some of the other elements on this list, platinum can exhibit spin alignment and is often used in electronic devices such as hard disk drives and fuel cells.

Would a science paper ever say “a billion percent”?


Goliatheos OP t1_jaan6om wrote

In the fourth paragraph. ”in fact, it’s a seven magnitude increase in conductivity. To put it another way, that’s a boost of one billion percent.”

Seems like anyone can publish anything and call it a scientific paper these days. Or was that always the case?


Thoughtfulprof t1_jacd6jq wrote

While that's true, this article is about a journal article published in Nature.


GreySkies19 t1_jac6evh wrote

That largely depends on the Journal it’s published in. Anyone can make a website and call it a scientific Journal, accept crap (often for money) and send it out into the world. Established Journals on the other hand are much better at vetting the research, have higher standards than even they themselves used to have and generally publish high-quality studies.

In conclusion: there’s Scientific Papers and “scientific papers”. Check the source.

Thanks! My comment wasn’t about this particular Journal article though. I simply responded to the question about publications in general with an answer about publications in general.

No, but this isn't a science paper. This is a popular science article so they use words like "quirky"

Yea! Real science papers talk about charming quarks!


Lurker_IV t1_jac7fd6 wrote

Very interesting! I was first confused because running electricity creates its own magnetic field so wouldn't running electricity through the material drop its own resistance itself?

Turns out the paper addresses that issue: yes it does, but it takes several minutes to force the current through the material. So the external magnetic field reduces that time from minutes to 0 time. There are so many ways this material could be used for cool things.

From my understanding of physics we should now be able to create arc reactors that can power a humanized mech suit indefinitely with a single one time charge.

Yes, quite a exquisite proposal. I understood everything, but can you please elaborate for some of the less intelligent.

Huh, I did my master's dissertation a long time ago on a theoretical analysis of spin-orbit coupling in perovskites. I was quite lazy and didn't do a very good job, but this is quite interesting, not often I hear the term these days :)
