Abstract

Low-field (100 Oe) DC susceptibility zero-field-cooled (ZFC) and field-cooled (FC) measurements (using a SQUID magnetometer) have been made on a Fe2MnSi single crystal. This compound exhibits a complex magnetic behaviour involving a transition from a paramagnetic state to a ferromagnetically ordered state at Tc ∼ 220 K, followed by a transition to a low-temperature reordering phase at TR ∼ 60 K. Results confirm previously observed demagnetising effects from polycrystalline samples with similar compositions. Also, the ZFC measurements along separate crystallographic directions show that the magnetization increases most readily in the [1 0 0] direction compared with that of [1 1 0], indicating a form of anisotropy in the complex low-temperature phase in Fe3 − xMnxSi alloys. The FC measurements at this field are demagnetisation limited even in the re-ordered phase.
