Abstract
Magnetic metallic glasses have enormous technological importance in, for example, magnetic recording, magnetic refrigeration and the construction of electrical transformers and motors. Traditionally these amorphous materials were prepared by melt spinning to form ribbons. Bulk magnetic metallic glasses based on the quaternary alloy Pd-Ni-Fe-P exhibit interesting phase behaviour depending on temperature and applied magnetic field. For the alloy of Pd40Ni22.5Fe17.5P20, paramagnetic, superparamagnetic, ferromagnetic and spin glass regions are all evidenced (Shen et al. J. Appl. Phys. 85, 4110, (1999)). It is proposed that the complex phase transitions may be due to the frustration caused by competing interactions between magnetic clusters presented in the material. We will present preliminary findings from neutron depolarization studies on the alloy of Pd40Ni22.5Fe17.5P20 as a function of temperature (RT to 10K) and applied magnetic field up to 11T. © The Authors
