Photomagnetic effect in n-type InSb at 77 °K

The steady-state odd photomagnetic effect was studied at liquid-nitrogen temperatures (77 °K) in n-type InSb having a carrier density of 4.2 · 10¹⁶ cm^-3. When the rate of surface recombination on the illuminated surface is higher than on the dark surface, the photomagnetic effect becomes negative in suitable magnetic fields.Translated from Izvestiya VUZ.
