This paper investigates how magnetic fields penetrate size-quantized systems, revealing non-uniform current distributions and discussing potential NMR observation methods.

Contribution

It provides a detailed analysis of magnetic field penetration and current distribution in quantum wells with size quantization, including potential experimental detection techniques.

Findings

Non-uniform distribution of diamagnetic and paramagnetic currents

Magnetic field distribution within quantum wells analyzed

Potential observation via NMR discussed

Abstract

The magnetic field, applied to a size-quantized system produces equilibrium persistent current non-uniformly distributed across the system. The distributions of dia- and paramagnetic currents and magnetic field in a quantum well is found. We discuss the possibility of observation of field distribution by means of NMR.
