Abstract
The spin flip transition at Ts f=123 K in chromium is described by assuming the existence of a uniaxial magnetic anisotropy and magnetoelastic interaction. The measured strains occurring at Ts f and measured elastic constants imply the following magnetoelastic tensor elements in units of 105 erg/cm3: (F1 1−F1 3) =15.2, (F1 2−F1 3) =1.8, (F3 1=F3 3) =−9.1. For 95 K<T<Ts f, spin flop experiments imply that the anisotropy constant K is K(T) = (.32×103)(T−Ts f) erg/cm3. From estimates of χ⊥ and K at T=0, the q=0 spin wave energy is estimated to be about 9 cm− 1. The stress dependence of Ts f is calculated from the model.Keywords
