The temperature dependence of magnetic properties for Nd60Al10 Fe20Co10 bulk metallic glass is investigated. The re sults indicate that th e Nd60Al10Fe20Co10 bulk metallic gla ss exhibits permanen t magnetic behaviour at room temperature. The coercive force and the shape of hy steresis loops change markedly when temperature decreases. AC magnetic susceptib ility is measured and a peak at about 18K is found. The peak moves torwards high temperatures when the frequency is increased. This indicates that there are spi n glass structures in the bulk metallic glass.
