Magnetic structure of the surface and interior of Ba hexaferrites
Kamzin A.S., Ol'khovik L. P., Rozenbaum V. L.
The magnetic structure of the surface layer of single crystals of Ba hexaferrites has been studied in direct comparison with the magnetic structure of the interior of the sample by a method involving simultaneous y, x-ray, and electron Mossbauer spectroscopy. Within the experimental error of ~ 10 nm, the results do not reveal a surface transition layer in which the orientation of the magnetic moments changes smoothly from the direction observed on the surface to the direction in the interior. In antiferromagnets, on the other hand, the thickness of this transition surface layer is hundreds of nanometers. © 1995 American Institute of Physics.
