While there are many techniques by which the temperature dependence of the magnetization can be probed, many suffer the disadvantage that not only the signal from the magnetic layer but also from the paramagnetic substrate are recorded. Here, optical techniques provide an essential complementary measurement with which only the surface of the sample is probed up to the skin depth-200-300A. A sensitive temperature and wavelength dependent magneto-optic Keff Effect spectrometer was built using an intensity stabilized argon ion laser, a continuous flow cryostat and conventional optics necessary to probe the in-plane magneto-optic Keff effect signal.
