Oblique-incidence Sagnac interferometric scanning microscope for studying magneto-optic effects of materials at low temperatures.We describe an oblique-incidence zero-area Sagnac interferometric microscope for studying spatial and temperature dependence of magneto-optic (MO) effects in samples under cryogenic conditions.  The inherently high sensitivity and the capability of detecting a magnetization without external modulation makes such a Sagnac interferometric microscope particularly useful for studying magnetic effects in novel materials at low temperatures.
