<p>This invention involves resonance enhancement of signals obtained from magnetic specimen (S) undergoing changes in magnetic state. This is accomplished by placing the sample (S), magnetized by a quasi-static magnetic field, in a high frequency resonant cavity (R). By adjusting the resonance frequency of the sample-containing cavity (R) so that it is resonant at a d.c. field corresponding to domain wall motion or domain rotation, clear signals can be obtained from the sample.</p> |
