Ferromagnetic Resonance Experiments on Crystal-Oriented Hexagonal Ferrites

摘要

Ferromagnetic resonance was measured on crystal-oriented samples of the Co delta Ti delta M series prepared by means of topotactical reactions. Samples with a high degree of alignment were obtained with anisotropies ranging from +6000 oe (uniaxial) to -4900 oe (planar). Resonance conditions can in general be described by existing theories, developed for single crystals of hexagonal crystal structure. Line width measurements on these materials are also viewed in the light of existing theories. (Author)
