We report significant temperature dependence of the transverse electron g∗‐factor in symmetric lead chalcogenide multi‐quantum wells (MQWs). The g∗‐factor values were extracted from the electron Larmor precessions recorded by means of a circularly polarized pump probe technique under the influence of transverse external magnetic field (Voigt geometry) in the temperature range between 10 and 150K. The reported g∗‐factor values are in good agreement with theoretical predictions and available low temperature experimental data. Although temperature tuning of lead salt laser emission wavelengths has been the method of choice in these systems for many years, we demonstrate that temperature can also be used to modulate g∗, and hence the spin lifetime in lead salt QW spintronic devices
