Abstract
Bulk amorphous alloys of composition Nd60Fe30Al10, Nd60Fe20Co10Al10, and Pr58Fe24Al18 have been prepared, and all alloys exhibit hard magnetic properties at room temperature. Magnetic field sweep rate measurements show the intrinsic coercivity to be proportional to the logarithm of the field sweep rate. The fluctuation field, Hf, for each alloy, is determined from both sweep rate and magnetic viscosity measurements. In the case of the latter it is determined by using both the waiting time method and S/χirr, where S is the magnetic viscosity parameter and χirr the irreversible susceptibility. Differences in the value of Hf determined from the sweep rate and magnetic viscosity experiments are discussed, and the value of the activation volume for each alloy determined.
