Abstract

Quantum oscillations of the anomalous component of Hall resistance with unusually high amplitude that exceeds the amplitude of the Shubnikov–de Haas oscillations of the transverse magnetoresistance were detected in mercury selenide samples doped with low concentration of cobalt impurity. Such oscillations correspond to the magnetic quantum oscillations due to thermodynamic anomalous Hall effect which agrees with the predictions of the theory of the Hall effect for the systems with spontaneous spin polarization of hy-bridized donor electrons.
