Talk:Magnetic semiconductor

Untitled
This is one of the hot topics in condensed matter physics. Although it may be tempting to cite only the works where high Curie temperatures have been measured, many of these measurements actually have not been reproduced. The magnetic semiconductor conferences are like battlefields with one experiment contradicting the other, and for most materials there is no consensus on how high or low the Curie temperature is. Please be critical with references: a published article in most cases is not the truth.

Is it really necessary to mention that XXX at institute YYY did pioneering work? I rewrote the bit on H. Ohno, but removed the uninformative bit of T. Dietl (indeed his work is important and pioneering and deserves to be acknowledged, but whether his RKKY based model makes sense or not is another one of the unresolved questions). If someone comes up with a more accurate and informative statement than Tomasz Dietl from Institute of Physics Polish Academy of Sciences did pioneering work in theory to magnetic semiconductors, go for it.

GaAs:Mn is one of the few materials, where scholars agree that the Curie temperature is around 100–200 K, which I wouldn't call cryogenic. Will add reference(s) next time.

I agree that this is one of the hot topics in physics today, however, I found the previous entries missing the point dealing with the crucial requirements that link a material with high-Tc ferromagnetism. I added some discussion in the "materials" section dealing with experimental findings dealing with the importance of carriers. Indeed, some of the "controversy" in the field is due to unreported carrier concentrations and carrier type with the associated magnetic properties of the magnetic semiconductor. This is very true in the oxide semiconductor literature. I hope the additional writing helps bring forth more discussion on this interesting field.

It's probably worth mentioning the alternative theories that would account for magnetism in oxide semiconductors - e.g. that rather than achieving uniform doping, the dopants can segregate into secondary magnetic phases. —Preceding unsigned comment added by 163.1.19.120 (talk) 17:34, 15 March 2010 (UTC)

Merging ZnO based Diluted Magnetic Semiconductors
I was working on orphaned pages and there seems to be quite a large amount of overlap in these articles. There does not appear to be separate pages for other dilute magnetic semiconductors. I lack the necessary physics knowledge to perform a merger, but think the articles could be cleaned up a little bit. — Preceding unsigned comment added by LaunchAxis (talk • contribs) 06:41, 19 December 2012 (UTC)
