Title

A Magnetic and Mössbauer Spectral Study of the Spin Reorientation in NdFe₁₁Ti and NdFe₁₁TiH

Abstract

The influence of hydrogenation on the spin reorientation in the presence of neodymium was investigated in NdFe 11Ti and NdFe 11TH. The magnetic properties of these compounds were determined by utilizing ac magnetic susceptibility, thermomagnetic, and iron-57 Mössbauer spectral analysis. It was found that the these compounds had two advantages as hard magnetic materials such as: a high iron content yielding high magnetization and a high Curie temperature. The investigation results show that these compounds undergo a spin-reorientation transition at ∼185 K and at 100± K, from an axial magnetic phase at high temperature to a basal magnetic phase at low temperature.
