Disentangling magnetism and phonons in magnetostrictive CoFe2O4:
CoFe2O4 is a highly magnetostrictive material with a very high magnetic ordering temperature near 900 K. Preliminary triple-axis work has found sharp acoustic phonons, but... -
High temperature measurements of the spin wave dispersion in Yttrium Iron Garnet
Yttrium Iron Garnet (YIG) is a material with extremely wide ranging applications, having the narrowest ferromagnetic resonance linewidth of any known material. We have recently...
