The possible existence of the spin glass (SG) state in the (Cr84Re16)99.6Mn0.4 alloy was investigated using magnetisation measurements. The temperature dependence of magnetisation, M(T), indicated a splitting of the M(T) data in the zero-field-cooled (ZFC) and field-cooled (FC) curves at the pinning temperature, Tp which is an indication of magnetic anisotropy in the system. The (Cr84Re16)99.6Mn0.4 alloy showed time dependence of isothermal remanent magnetisation (IRM) measurements, which is a signature associated with canonical SG. Measurement of field dependence of magnetisation did not show saturation at the lowest temperature or highest magnetic field because of the lack of long-range magnetic ordering which is also a SG signature. Preliminary measurements indicate the possible existence of magnetic frustration leading to the SG state in the (Cr84Re16)99.6Mn0.4 alloy.
