Abstract :
An experimental analysis of the rotational remanence properties of various recording samples is presented. The locus of the saturation remanence is an ellipse. For smaller rotating fields, the trajectory is a spiral whose limit cycle is an ellipse; however, depending on the initial magnetization, the aspect ratio and the center of the ellipse for small fields are different from those for the saturating field case
