The MPGE stands for a photocurrent generation which requires simultaneously gyrotropy and the presence of a magnetic ﬁeld.10,11,12 The gyrotropic point group symmetry makes no diﬀer-ence between components of axial and polar vectors, and Webproposed for bulk gyrotropic crystals [18, 19]. The magneto-gyrotropic eﬁect ap-pears in the presence of an external in-plane magnetic ﬂeld and is caused by k-linear terms in electron{phonon interaction resulting in asymmetric excitation or asymmetric energy relaxation of heated by THz radiation spin polarized elec-tron gas [11]. ps 54 hillside
