Abstract
The effect weak (10–100 kA m–1) low-frequency (10–20 Hz) pulsed magnetic fields have on the surface structure and magnetic characteristics of yttrium–iron garnet Y3Fe5O12 is studied by means of electron and Mossbauer spectroscopy. A mechanism is proposed for the variation of saturation magnetization in Y3Fe5O12 after magnetic pulse treatment. The mechanism is associated with the change in the spin state of iron ions localized in the tetrahedral sublattice.
