ABSTRACT:
A method employing torque magnetometry for measuring magnetic properties of a workpiece, for example, measuring the anisotropy of a magnetic thin film. The present method utilizes a novel alternative to known methods of torque magnetometry, namely, employing a viscometer, as modified in accordance with the present invention. The present method preserves all the virtues of torque magnetometry, yet realizes method objectives of efficiency, low cost, and accurate measurement.
