We have studied theoretically the effect of electrical magnetochiral anisotropy (eMChA) in p-type tellurium crystals. It is shown that the terms kiBj in the hole Hamiltonian, linear in both the wave vector k and the magnetic field B, do not lead to eMChA and one needs to include the higher-order terms like ki3 Bj. Two microscopic mechanisms of the effect are considered. In the first one only elastic scattering of holes by impurities or imperfections is taken into consideration. In the second mechanism, besides the elastic scattering processes the hole gas heating and its energy relaxation are taken into account. It is demonstrated that both contributions to the magneto-induced rectification are comparable in magnitude. The calculation is performed by using two independent approaches, namely, in the relaxation-time approximation and in the limit of small chiral band parameter /3. A bridge is thrown between the eMChA and magneto-induced photogalvanic effects.
