Modified Sagnac interferometer for high-sensitivity magneto-optic measurements atcryogenic temperatures

Jing Xia, Peter T. Beyersdorf, Martin M. Fejer +1

We describe a geometry for a Sagnac interferometer with a zero-area Sagnac loop for measuring magneto-optic Kerr effect (MOKE) at cryogenic temperatures. The apparatus is capable o…
