Title

A High Field Magnetic Study of the Spin Reorientations in Nd6Fe13Si

Abstract

The field dependence of the magnetization in antiferromagnetic Nd6Fe13Si has been measured between 4.2 and 295 K under an applied magnetic field of between zero and 23 T. Isofield magnetization measurements at 1, 10, 15 and 20 T have also been carried out between 4.2 and 295 K. The magnetic phase diagram of Nd6Fe13Si contains three regions. The magnetic moments were aligned within the basal plane of the tetragonal unit cell and two critical fields were observed between 4.2 and 110 K. The critical field in the high temperature region was smaller that that observed in the low temperature region, indicating that the uniaxial antiferromagnetic exchange was weaker that the basal exchange.
