Orbital Magnetism in Disordered Mesoscopic Metals

TL;DR

This paper reviews and extends the theory of orbital magnetism in disordered mesoscopic metals, analyzing temperature, field effects, and sample-specific fluctuations in magnetic susceptibility and magnetization.

Contribution

It provides a comprehensive review and extension of the orbital magnetism theory, including fluctuations and sample-specific oscillations in disordered metals.

Findings

Sample-to-sample fluctuations cause aperiodic oscillations in susceptibility.

Magnetization exhibits sample-specific oscillations with changing magnetic field.

The theory is applicable across a broad range of temperatures and magnetic fields.

Abstract

The theory of orbital magnetism in disordered metals is reviewed, and extended to include a broad range of temperatures and fields. Sample-to-sample fluctuations in the orbital magnetic susceptibility are studied. In a given sample these fluctuations manifest themselves in aperiodic sample-specific oscillations of susceptibility and magnetization, when the strength of the magnetic field is changed.
