Magneto-optic Kerr effect measurement of 2D electron system at mK-temperature
ORAL
Abstract
We study high mobility 2D electron system using a high-resolution magneto-optic Kerr effect measurement at mK-temperature. With only 1uW probing light, we achieve 0.5urad Kerr angle resolution and 15um spatial resolution. We observe SdH-like quantum oscillation in our result.
