The variations of magnetization- and strain-induced anisotropy in metallic glasses (Fe1-xCox)78Si10B12 with composition and temperature have been studied. The magnetization- and the irreversible strain-induced anisotropy constants, Kam and Kusi, have positive values, the maximums of which occur at x=0.7 and 0.5 respectively. The reversible strain-induced anisotropy constant Kusr has a negative value except for x>0.975, the magnitude of which exhibits a maximum at x=0.7. As to the temperature dependence of Ku, a common relation Ku(T)=kMsα(T) is followed, in which a is a constant between 3.4 and 7.5 depending on the composition and the annealing condition used. Some of the experimental results are explained by using the concept of short range ordering.
