Electrochemical cell for in situ magneto-optic Kerr effect measurements

A unique electrochemical cell allows in situ magneto-optic Kerr effect measurements for magnetic characterization of ultrathin films, concurrently with electrochemical control. This durable, compact, and easy to assemble cell is mounted on a rotatable base which enables magnetic measurements in both the longitudinal (in plane) and polar (perpendicular to plane) configurations. Its utility in the reproducible preparation and in situ magnetic characterization of thin films is demonstrated with electrochemical and ferromagnetic hysteresis data for ultrathin Ni films (less than or equal to15 monolayers) electrodeposited on Ag(111) and Au(111) single crystal substrates.
