An anomalous positive magnetoresistance is observed in layers of GaAs and GaAs 0.94 Sb 0.06 doped with Ge (p‐type conductivity) which is found to be governed by quantum effects. In the analysis the degeneracy of the valence band is considered and the contribution extracted corresponding to the total moment, I = 0, of the pair of particles. The wave function phase relaxation time is found. The origin of the magnetoresistance which cannot be described by the theoretical expression for I = 0 is discussed.
