Ytterbium might appreciate the vote of confidence, but may not appreciate being called "it".

Ytterbium-Rhodium-Silicon?

First step towards Rhodomagnetism, and then we're all farked!

Isn't there a rule against calling out a Farker in the headline?

I read the words of that article and almost understood some of the concepts

Looking forward to buying spintronic devices if I live long enough.

Heh came here to say this, glad I looked first.

Fun fact:  Ytterbium is only one of the 4 elements names after a single small mining town in Sweden.

This was the first thing that came to my mind.

shiat.  i came here to look smart and post that.

(it really is quite remarkable, that fact.)

I'll tell you later.

I think ytterbium is pretty awesome.

"Metamagnetism" is when a material (usually this kind of quasi-stable crystalline compound) exhibits a very strong magnetic field in response to a relatively weak externally applied magnetic field, probably because some aspect of orbital geometry containing polar carriers is, well... metastable, as in it's at an inflection point and shoving it a little bit causes it to fall all the way into an energy valley to one side or the other.

The two(ish) "normal" types of magnetism, to review why there's a special word for this, are:

"ferromagnetism" where a persistent magnetic field is created by the alignment of permanent magnetic domains in the material (often crystalline grains within a polycrystalline metal)... "persistent" in that it continues after the external field is removed.  This one is not uncommon in single-element metals like, obviously, iron, thus the name.

"diamagnetism", where the presence of an external magnetic field instead causes a temporary induced magnetic field opposing the external field.  Technically basically everything does this to some extent, but it's more noticeable in materials with a magnetic permittivity less than that of empty space, and can be really strong in superconductors.  It doesn't generally persist after the external field is removed.

This has been your high-school chemistry lesson for today, subby.

// Two-ish because as with most things in science, there are about ten other jargon terms defining more specific circumstances.  It should surprise no one that one of the fundamental physical forces in the universe has a lot of specific cases involved in how it works.  You'll probably also note a lot of "generally" and "typically" in the above... same reason.

Glad to see this topic already covered. Yb is also producing goalies.

I'm not sure that's a good thing.  I'm of the opinion that having a child who wants to be a netminder is having a child with a mental disorder.

And three others were discovered in the same mine: holmium, thulium, and gadolinium. Ho ho ho.

I was going to post an image of the 1-3-7 crystal structure here which is really unusual here but the only searchable images out there are too messed up to bother. I'd describe it but it wouldn't do it justice dammit

No it's true. You have to be insane or superhman to willingly undergo that kind of stress. Fortunately my son is the stoic type with just a hint of cray.

So if you ever wanted to know why I picked this name, here's a list of why:
1. The scientist who discovered it was Swiss and I'm part Swiss.
2. I was born in 1970.
3. Yb is a state of mind.
4. I have impeccable timing.
5. Xenotime crystals are beautiful
