Medium resolution magneto-optic Faraday rotation measurement setup has
been reported. Measuremental setup reported is made up of simple pola
rized laser source, beam expander, analyzer and a bisected cross polar
ized p-n detector for single ended measurements. Result of CoO modifie
d yttrium iron garnet (YIG) films showed a rotation of 3 deg/mu m whic
h is comparable to earlier reported Co-doped YIG films.
