| 摘要 |
This invention involves resonance enhancement of signals obtained from magnetic specimen undergoing changes in magnetic state. This is accomplished by placing the sample, magnetized by a quasi-static magnetic field, in a high frequency resonant cavity. By adjusting the resonance frequency of the sample-containing cavity 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.
