Magnetic Manifestations of Carrier Confinement in Quantum Wells

Abstract

A combination of superconducting integrated circuits was used to construct a very sensitive magnetooptic microsusceptometer for observations of the optically induced magnetization in Cd1-xMnxTe multiple quantum wells. Spin-polarized electrons and holes are created optically, and the quantum mechanically localized wave functions of the carriers then serve as microscopic probes of the magnetic behavior. Both the magnitude and the picosecond dynamics of the magnetic response have been studied and reveal the effects of carrier quantization. © 1989 The American Physical Society.
