Abstract
A simple and inexpensive device rather sensitive to studies of magnetic properties of very thin (0.5–0.6 nm) ferromagnetic films by the surface magnetooptic Kerr effect (SMOKE) method in ultrahigh vacuum (UHV) conditions is described. The system is intended for measuring both longitudinal and transversal Kerr effects. The special vacuum-tight electromagnet system of the SMOKE device is quite compatible with other surface-sensitive methods. When an additional external magnet system is used, the same optical and electronic system can be also employed for ex situ investigations. Examples demonstrating the high sensitivity of this setup and its efficiency during studies of the magnetic anisotropy are given.
