SIZE EFFECTS ON THE DIAMAGNETIC SUSCEPTIBILITY OF A FREE ELECTRON GAS.
Abstract
A noninteracting electron gas constrained in one dimension by an harmonic oscillator potential is used as a model of a metallic film with specular surfaces. The diamagnetic response of this system to an applied field is investigated to study the effect of sample size on both the de Haas-van Alphen oscillations and the steady susceptibility. When the diameters of the dominant cyclotron orbits become comparable to the effective sample 'thickness,' we find large departures from the familiar 1/H law for the dH-vA oscillations. However, the steady part of the susceptibility appears to remain independent of size. (Author)
