Abstract

The design of a wideband decimeter-wave (200–900 MHz) spectrometer with a magnetic induction of up to ∼10 T is described. This spectrometer is intended for studying electronic-nuclear oscillations in antiferromagnets at low temperatures (4.2−1.3 K). Critical field H c = 2.5 ± 0.3 T of a reorientation transition in a noncollinear antiferromagnet Mn3Al2Ge3O12 at temperature T ≈ 1.3 K was determined from a 55Mn2+ NMR spectrum.
