The Temperature Dependence of the Three-Dimensional Analogue of the Quantum Hall Effect in Semimagnetic Hg$\text{}_{1-x}$Fe$\text{}_{x}$Se

Due to the pinning of the Fermi energy to a localised donor state in Hg$\text{}_{1-x}$Fe$\text{}_{x}$Se the free carrier concentration oscillates in an applied external magnetic field. We measured the resulting modulations of the Hall resistance in fields up to 17.5 T and at temperatures between 4.2 K and 30 K
