The influence of an externally applied magnetic field on the properties of an exciton confined in a quantum disk are investigated. The confinement potential is a hard wall of finite height. Finite difference techniques are used to solve the two‐particle Schrödinger equation. The dependences of the diamagnetic shift on the effective mass and disk radius are studied. Our theoretical results compare well with the experimental results of Wang et al. [Phys. Rev. B 53 , 16458 (1996)].
