graphene magnetism

Posted by reverendgraham on 2010.0805.1943

I am going to take advantage of this amazing "forum" contraption to bring to Our Attention the latest news from the world of graphene, which I have already blogged about recently enough that it would seem distasteful to repeat myself already in that medium, yet which is, of course, of great interest both to myself and to the hexagonal community at large (but I repeat myself!) [EDIT: the forum as such no longer exists]:

Gigantic Pseudo-magnetic Fields Created
Graphene, the extraordinary form of carbon that consists of a single layer of carbon atoms, has produced another in a long list of experimental surprises. Researchers report the creation of pseudo-magnetic fields far stronger than the strongest magnetic fields ever sustained in a laboratory — just by putting the right kind of strain onto a patch of graphene. . . ."

Graphene bubbles mimic explosive magnetic field
"Electronics engineers would love to play with super-powerful magnetic fields – if only they weren't so likely to cause explosions. Now it turns out that graphene can mimic the useful effects of such a magnetic field, offering a new way to control the super-material's remarkable electronic properties. . . ."

I picked these two articles more or less at random, but there are plenty more on this subject in the hexagonal news.

I have more to say on the subject, but I think I will, in fact, save it for another Hexblog post at some point in the future (I am trying to build up a nice queue of subject matter in my mind, so I will always have something to rant about when the mood strikes me). I AM WONDERING THOUGH IF ANYONE HERE—among my faithful throngs of followers—HAS ANY THOUGHTS ON THE ADVENT OF GRAPHENE AND ITS MYRIAD IMPLICATIONS?

Well that's fascinating, Reverend. Also if interest I feel is the recent development of "white graphene"—it's like regular graphene, you see, but white.

Actually it's not graphene at all, it's just boron nitride. I am having a hard time understanding why they even call it "graphene." Perhaps they just want to get on the graphene bandwagon. It is very hexagonal though.

Also of interest: nanomesh. Ftvw.
