Abstract

Magnetic properties of amorphous GdxLa65-xCo25B10 are investigated from 4.2 to 300 K. AC susceptibility and magnetization measurements to 80 kOe are used to determine a phase diagram including paramagnetic, ferrimagnetic and spin-glass regions. For x ≲ 40 diffraction and susceptibility data indicate the increasing development of chemical short-range order and phase separation. An analysis of the magnetic structure and local-moment magnitudes is presented. Results of a scaling analysis for one paramagnetic-ferrimagnetic transition are discussed and some conclusions are drawn concerning the relationship between phase transitions and chemical short-range-order in ternary or higher-order magnetic glasses.
