Method and apparatus for detecting magnetic zylinderdomaenen in magnetic crystal films with the aid of ferrimagnetic resonance

摘要

A method of detecting movable cylindrical magnetic domains produced in a magnetic crystal film supported on a substrate in which a microwave signal is transmitted into a restricted region between two planar conductors by means of a ferrimagnetic resonance mode, and the presence of a domain is detected from the measuring signal variation when the echoes of elastic waves in the film vary.
