I thought the spinsters in this crowd would find the following article rather interesting: http://phys.org/news/2015-08-magnon-phonon-magnetoelastic-magnetic-photoexci tation.html
They describe anomalies involving interactions of spin-domain boundaries and photonic energy. Here is a relevant quote from the phys.org overview article: > The scientists also observed a transition from spin wave to > magnetoelastic wave excitations by increasing excitation intensity, > a process which Ogawa acknowledges is not entirely understood at present. > "It's the first time that this effect has been observed - but it seems very > plausible that the coupling of light to matter and the energy transfer of > the light to the magnetoelastic waves involve some non-linear processes." I'd love to hear further interpretation of these findings from this group. Best wishes, -Bob Ellefson
