Abstract

The magnetic properties of the Heusler compound Co2NbSn have been investigated. Whereas Co2NbSn is paramagnetic above T-c = 116 K, it changes into a ferromagnetic state below T-c. Based upon the observation of an anomalous thermomagnetic irreversibility below T-c we argue that this indicates the presence of narrows Bloch walls, probably caused by large magnetic anisotropy induced by a structural transition at T-s - 235 k.
