摘要：
Heterostructures containing CdMnTe-diluted magnetic semiconductor quantum wells are proposed as magneto-optic layers (MOL) for high-resolution Faraday microscopy at low temperature. The Faraday rotation is enhanced up to 54.4 deg T-1 by embedding the quantum wells in a semiconductor-metal optical cavity. These MOL allowed the observation of the intermediate state pattern in a superconductor layer with spatial and magnetic resolutions of 1 mum and 10 mT, respectively.
