Angular distribution of rotational hysteresis losses in Fe-3.25%Si single crystals with orientations (001) and (011)

Measurements have been made of the difference torque
\DeltaM
(for the same angle φ) acting on a ferromagnetic material during the rotation of the magnetic field through 360° in opposite directions, depending on the angle φ of the magnetic field rotation and on magnetization ratio
(I/I_{s})
. The dependence
\DeltaM
on the angle φ is known as the angular distribution of losses. Experiments have been carried out on Fe-3.25%Si single crystals in the form of disks with surfaces parallel to the
