Abstract

Magnetic and transport properties of stoichiometric Mn₃ In compound are extensively studied by means of dc magnetization, ac susceptibility, magnetic relaxation, and electrical resistivity measurements. It is found that Mn₃ In is a ferrimagnet with Curie temperature of 80 K and that a metallic spin-glass-like (SGL) state exists below 45 K, which is indicated by the difference between zero-field-cooled (ZFC) and field-cooled (FC) magnetization curves, invariable FC moments, large remanence effect, magnetic relaxation, and electrical resistivity abnormality. Moreover, the SGL state in Mn₃ In exhibits some anomalous behaviors, such as no cusp in the ZFC curve at the frozen temperature T_f, a remarkable high-field irreversibility, and a high-field relaxation process. The presence of the SGL state in the Mn₃ In compound without doping or substitution is discussed in terms of magnetic cluster mode.
