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 1H law for the dH-vA oscillations. However, the steady part of the susceptibility appears to remain independent of size. Author
