Abstract
This paper describes the application of a Cahn RG electrobalance for measurements of the magnetic parameters of thin ferromagnetic films. By a suitable conversion of the microbalance into a torque-measuring device, the static hysteresis loops and torque curves can be directly recorded. From the recorded data the main magnetic properties of the films, such as saturation magnetization, remanence, coercive force, and the induced anisotropy constant can be evaluated with high accuracy. Examples of hysteresis loops of various ferromagnetic films with thicknesses ranging between 200 and 2000 Å are given.
