Experimental results are given of galvanomagnetic measurements of p‐HgTe in strong pulsed magnetic fields performed up to 35 T in the temperature range 77 to 340 K. Co cen‐tration and mobility of holes in the intrinsic conductivity region were determined. To explain the experimental data it is necessary to introduce a valence and conduction band separation of 0.6 meV/1 T induced by magnetic field. The temperature dependence of the mobility shows that the hole mobility is limited by phonon scattering.
