Abstract : A zero-magnetic-field maser was operated at a frequency of 81.3 gc with the iron ion in rutile, a zero-magnetic-field maser was operated at a frequency of 78 gc with the iron ion in zinc tungstate, and the first reported paramagnetic resonance absorption was observed at frequencies near 330 gc with the manganese ion Mn(3+) in rutile. Since the 330-gc paramagnetic resonance experiments were very crude, a more sophisticated system is being designed. (Author)
