Can I read Anomaly in the field dependence of the anisotropic magnetic susceptiblity of a single-grained α-Mn on EtoBox?

Anomaly in the field dependence of the anisotropic magnetic susceptiblity of a single-grained α-Mn by Hiroshi Nakano; Masahiro Mori; Yorihiko Tsunoda; Susumu Matsuo is a Materials Science article available to read on EtoBox.

What is Anomaly in the field dependence of the anisotropic magnetic susceptiblity of a single-grained α-Mn about?

A kink was observed near 20 kOe in the field dependence of the magnetization in a single-grained a-Mn without a magnetic hysteresis below the Neel temperature in an accurate magnetization measurement below 80 kOe. It was observed along [1 0 0], [1 1 0] and [1 1 1] crystallographic directions. The field dependence of the magnetization above 40 kOe extrapolates to positive finite magnetization at null field. The kink suggests a weak metamagnetism induced by the external magnetic field. A small but clear anisotropy was observed between the weak-field susceptibilities along [1 0 0] and [1 1 0]/[1 1 1] directions. A previously reported large susceptibility anomaly was not affirmed between 90 and 270 kOe.
