Abstract

The structure and magnetocaloric properties of the Fe-doped HoTiGe compound were investigated by means of scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), x-ray diffraction (XRD), superconducting quantum interference device (SQUID) magnetometry and calorimetry. As with the early studies on the undoped compound (1-3), the Fe-containing alloy exhibited an antiferromagnetic-to-paramagnetic transition and a magnetocaloric effect peak at 90 K. However, the Fe-doped alloy contained three minor phases in addition to the HoTiGe majority phase. The magnetization (M) versus temperature (T) data showed peaks at 10 K and 90 K, while M vs. field (H) curves showed the presence of a field-induced transition for all T
