High Field Torque Magnetometry Measurements on Y1.8Er0.2Fe14B


The magnetocrystalline anisotropy energy has been determined for single crystal Y1.8 Er0.2Fe14B in the (001) and (100) planes between 5 K and 300 K using torque magnetometry techniques. The results are compared with a model based on crystal field theory. Excellent agreement was obtained between the model and experiment. Both experiment and model showed a first order spin reorientation between the [001] and an angle 70 degrees from the [001] in the (100) plane.
