<jats:title>Abstract</jats:title><jats:p>The photoconductivity and the photomagnetoelectric current in low‐concentration, high‐lifetime Pb<jats:sub>0.83</jats:sub>Sn<jats:sub>0.17</jats:sub>Te samples are measured at strong optical excitation using a Q‐switched ruby laser. At quantum flux Q > 2 × 10<jats:sup>21</jats:sup> cm<jats:sup>−2</jats:sup>s<jats:sup>−1</jats:sup> nonlinear recombination is observed. From the characteristics measured the coefficient of Auger recombination <jats:italic>C</jats:italic> = (4.5 ± 1) × 10<jats:sup>−27</jats:sup> cm<jats:sup>6</jats:sup>s<jats:sup>−1</jats:sup> is obtained. The results are confirmed by lifetime data obtained at low excitation levels.</jats:p>
