| Abstract: | Temperature dependences of the forced volume magnetostriction dω/dH and the saturation magnetization σs for (CoTm)90Zr10 (Tm = Cr, Mo) amorphous alloys have recently been measured by the 3-terminal capacitance method and a vibrating sample magnetometer and magnetic balance at temperatures from 77 K to the Curie temperature Tc or the crystallization temperature. The pressure coefficient of σs0 at 0 K, d ln σs0/dp, is estimated from (dω/dH)0 extrapolated to 0 K using the thermodynamical relation. The values of d ln σs0/dp increase in negative value with increasing Tm concentration. The relation between d ln σs0/dp and the pressure coefficient of Tc, d ln Tc/dp, estimated indirectly from dω/dH is discussed. |
