The magnetocaloric effect of Fe91-x Mo8 Cu1 Bx (x=15,17,20) amorphous alloys has been studied. The temperature of the peak of magnetic entropy change can be tuned by altering the FeB ratio in the alloy, without changing its magnitude, ∫Δ SMpk ∫. The average contribution of the Fe atoms to ∫Δ SMpk ∫ increases with increasing B content. This is correlated with the increase in the low temperature mean magnetic moment of Fe. A recently proposed master curve behavior for the magnetic entropy change is also followed by these alloys and is common for all of them.
