Аннотация: In the magnetic field range Delta H = 8-60 kOe we observed and studied the anomalous oscillations in the magnetic field dependence of the resistance and magnetization of single crystals of n-HgCr2Se4. The absence of periodicity in 1/H in the Delta H = 8-20 kOe range can be explained by the non-Fermi-liquid behavior of the electron Показать полностьюsubsystem and agrees with the theory of the de Haas-van Alphen in systems with intermediate valence. In stronger fields, Delta H = 20-60 kOe, the amplitude of the fundamental harmonic decreases, with the number and amplitude of the higher-order harmonics increasing, As a result, noise is superimposed on the signal as magnetic field strength grows. The temperature dependence of the magnetization is the sum of the monotonic spin-wave contribution and the oscillating part. (C) 1998 American Institute of Physics. [S1063-7761(98)02205-7].
