Abstract:

The construction of a new zero-field paramagnetic resonance ZFPMR spectrometer is discussed. Spectrometer organization and construction details are presented for both resonant cavities and broadband traveling-wave helices as sample holders. A new circuit diagram for a square wave magnetic field modulator with fast time is given. The performance of each kind of spectrometer is discussed with particular emphasis on investigation of paramagnetic rare earth ions with zero-field splittings in diamagnetic host lattices.
