The theory of the photomagnetoelectric effect (PME) is studied in the case in which the recombination mechanism gives rise to a square‐root relationship between carrier densities. The nonlinear continuity equation is solved and analytical expressions of short‐circuit PME current I PME and photoconductance Δ G are found in the case of strongly absorbed light. The dependence of I PME and Δ G on the light intensity is studied by assuming as an example a three level recombination model. The main results of the analysis is that the I PME vs. Δ G behaviour shows the same power law as the charge carrier do.
