Abstract
Low field dc susceptibility, thermoremanent magnetization, and hysteresis studies are presented for two amorphous Fe-Mn-P-B-Al alloys of concentrations close to, and on either side of, the multicritical point in the magnetic phase diagram. They exhibit spin-glass and para-ferro-spin-glass transitions, respectively. For the spin-glass alloy, the Edwards–Anderson-type order parameter deduced from the dc susceptibility is found to yield a mean-field-valued critical exponent. In the alloy with two magnetic transitions, the temperature dependence of the thermoremanence and hysteresis indicate a ferro-spin-glass transition temperature consistent with that deduced from a scaling approach for the same alloy system.This publication has 22 references indexed in Scilit:
