Development of a versatile SMOKE system with electrochemical applications

We describe the design, construction, and implementation of a simple and inexpensive, yet versatile surface magneto-optic Kerr effect (SMOKE) setup designed to operate in conjunction with the electrodeposition of magnetic layers both in situ and ex situ. The system is based on a homemade electromagnet and commercially available components. The sensitivity of the system is demonstrated by measuring ex situ SMOKE hysteresis loops of Co thin films (down to three monolayers thick) electrodeposited onto a Au(111) electrode substrate.
