Dependence of the intensity of electron spin resonance on the photon momentum
Sheka V. I., Khazan L. S.
The interference of paramagnetic and combined resonances in crystals of the sphalerite type is analyzed. A relationship is established between the absorption intensity and the photon momentum which explains the experimental results of Dobrowolska et ah [Phys. Rev. Lett. 51, 134 (1983)]. The parameter in the term ~ к3 in the energy for a band electron in InSb is found for the first time.
