Electron Spin Resonance in Antimony

Electron spin resonance of conduction electrons in antimony has been investigated at 34.3 kMc/sec and 1.5^∘{}K. The results were consistent with the theory of Cohen and Blount for the g factor of conduction electrons in Bi and Sb. The principal axes of the g tensor coincided with those of the tilted-ellipsoidal Fermi surface. The parameters of the electron spin resonance were determined to be g₁=3.4, g₂=29.5, g₃=3. Resonance was also observed from transitions that involved both an orbital transition and a Zeeman transition.
