Abstract
The rotational hysteresis energy losses have been measured as a functi on of the applied field in particles for magnetic recording, where the magnetic anisotropy is varied with addition of doping ions (magnetocr ystalline anisotropy) or with densification of particles in the assemb lies (shape anisotropy). Both the values of the rotational hysteresis and the range of field where the losses occur result strictly related to the magnetic anisotropy and to its evolution.
