Useful spin or just spin?

Work at Ohio State University (researchnews.osu.edu/archive/thermospin.htm) with GaMnAs has opened up the possibility of (self) powering electronics from heat by converting the later into electron spin. The team are looking at looking at a hybrid technology thermo-spintronics for siphoning off waste heat to run additional memory or computation. The low temperature growth of GaMnAs is just one of the many areas of MBE reserach that has benefited enormously from the use of the kSA BandiT substrate temperature measurement system www.k-space.com/Products/BandiT.html, which has highlighted important effects completely invisible to other techniques.
