“…The higher the Tc was, the larger the Hc at 10 K became. The high coercivity obstructed the magnetization of the samples at low temperature and thus led to another characteristic of typical spin glass behavior, that is, the decreasing magnetization under a very low magnetic field from Tf to 10 K [8,28,30].
