Abstract

Systematic dHvA studies on the γ oscillation in lead have been performed deliberately choosing the specimen crystal consisting of two subgrains with slight misorientation; our intention here is to clarify the origin of the anomalous beat which has been frequently observed in addition to the well-known 42.5 cycle beat. It has been found that the anomalous beat appears periodically and that its angular dependence can be described by H ∝ θ where H is the magnetic field at which the anomalous beat is observed and θ (≪1) is the angle which specifies the magnetic field direction measured from the suitably chosen specimen axis sufficiently close to [011]. These results are successfully interpreted on the basis of Van Dyke's model of the third zone electron arm coupled with the microstructure of the specimen crystal. This conclusion is in agreement with the suggestion by Anderson et al. (1975) concerning the third zone electron arm in lead.
