  Anisotropic magnetostriction of an amorphous itinerant magnetY2Feand a simple random crystal-field model

  摘要：

  The anisotropic magnetostriction lambda(t) and the magnetization an measured for the amorphous Y2Fe intermetallic compound in the temperature range 3-300 K, in magnetic fields up to 9 T, Thr low-field sc (1 Hz) susceptibility shows a cusp at T-SG=3 K typical of spin-glass freezing. At 3 K and 9 T the magnetic moment of iron atoms is as small as 0.175 mu B, but the magnetostriction is found to be lambda(t) congruent to 16 x 10(-6). The magnetostriction results are interpreted within a random-crystal electric-field (RC-EF) model, which is a simplified band version of the random anisotropy model for localized magnetic moments. Good agreement is found between the thermal dependence of lambda(t) (9 T) and the model calculation, showing that a-Y2Fe is a spin glass but of random magnetic anisotropy origin (speromagnet). The model shows an enhancement of lambda(t) by the RCEF near the band electron filling, with lambda(t) peaking at the model RCEF parameter value.
