We report the anomalous Hall effect and nonuniformities introduced by aging in the bulk polycrystalline HgTe, which was grown in a predetermined profile, and measurements were taken in the temperature range of 82–350 K. It is found that anomalous behavior is caused by domain formation which is due to acceptor states and this domain formation effect gets diminished by annealing the sample in a mercury atmosphere.
