Doppler-Shifted Ultrasonic Spin Resonance in Metals

Abstract
A new method of measuring the conduction-electron g factor by ultrasonic Doppler-shifted spin resonance is presented. A Boltzmann-equation approach is used to obtain the attenuation arising from both the self-consistent-field and the Yafet mechanisms. The magnitude of the spin-dependent part of the attenuation is too small at the usual ultrasonic frequencies to be observed directly but the derivative of the attenuation should be observable.
