Really very cool, I've been using meetup and the website is just absolutely trash so any alternative is very welcome

I've seen this concept of using LLM/AI/etc for high throughput discovery of materials so, so often in the past 5 or so years and yet there hasn't really been any impact as a result.

I think this is the first one that has actually taken the pain to say how many of the discovered materials are actually feasible which is a real step in the right direction. Probably worth keeping in mind the step beyond plausible synthesis which is the actual cost/effort of the material. There's not much point if you find out RuO2 would be better than SiO2, as an example, if Ru is orders of magnitude more expensive.

A challenge I think you'll run into is that I expect the biggest companies (e.g. IBM) will already be doing the part they need themselves. I heard tell of IBM in particular using ML to improve their own chips before LLMs came along, so I'd be shocked if these bigger companies weren't already doing this for their own problems. Also, if you aren't doing the experiments yourself, it's always going to be a challenge to find a partner to test things for you and this will probably be the major time sink.

These things are interesting but for the most part quite dull and very industry-facing. Just mash together a bunch of random elements and see if it improves the thing you want to optimize.

The kids at private schools are specifically primed for every part of the application process, including the interview and interview questions in a way that state schools simply cannot. It does not matter how smart you are if your competition is able to practice in a way you cannot.

Honestly, when it comes to hacking things together with matplotlib I outsource all of my thinking to chatgpt to do the 80% of doc hunting that is honestly not worth it since everything in matplotlib is labelled inconsistently.

More to the point, when you write an article like this foretelling the doom of the american economy, why would you think you are able to brain drain any country? What stops the countries you are trying to drain from offering better incentives to stay?

This is not really as simple as just going through the permutations. What this is in practice is a triumph of instrumentation. Before this, no one has imaged altermagnetic domain structure. The behaviour of these materials is intrinsically linked to what happens in the micro- (or nano-) structure.

There are two challenging things here that makes this a discovery. One, making the material, which is extremely difficult to verify as altermagnetic due to the nature of measuring these materials. Two, the measurement, which combines two techniques to distinguish this as separate from antiferromagnetism.

It is a huge push forwards for the budding field since it provides a really nice way to go to a large-scale synchrotron with your altermagnet and study it in detail.

To add a bit more to this, it's really a new class of magnetism. Traditionally we might think of ordered magnetic materials as being one of two: ferromagnets, which is what you think of when you think of magnets, and antiferromagnets. Antiferromagnets locally order their magnetic moments antiparallel so any which way you measure it, you measure no magnetization.

The application is this: We would like to use ferromagnets and spin currents to make spin-electronic devices ("spintronic") where only the spin information is transferred without any large electrical currents. The goal of this is to save energy from Joule heating as spin can flow with significantly lower energy dissipation.

Ferromagnets run into a lot of problems: they have a stray field, so patterned elements will interact and interfere with each other that sets a limit on how dense each nanostructure can be. Antiferromagnets have a big problem: they are extraordinarily difficult to measure and that is a challenge to overcome.

So the benefit that altermagnetic materials presents is a clear union that tries to overcome the problems of both while retaining the strengths of both.

The exact definition of the ordering of an altermagnet is a bit subtle and it mostly comes from an understanding of how the electronic band structure is different as compared with normal antiferromagnets.

Ultimately they still live in the country. They have ties to it. Their assets and wealth may be tied up in the country which is difficult to extricate. And, most importantly, their friends, family and life are in that country. It is absurd to think that it is so easy for people to just pack up and leave a country.

I admit to not really being familiar with either, but it seems that this allows you to display comments alongside the paper in the browser, which is a very nice feature (and overall has a nicer coat of paint). At first blush, I find it a bit more difficult to figure out what the point of scirate is and how it should be used.
