The photosensitivity of GaAs tips is studied in a scanning tunneling microscope. Measurements of surface photovoltage and zero-bias photocurrent vs. incident light power are presented together with a simple theor. model. It is shown that these tips can be used for measurement of local sample magnetization through the magnetooptical Faraday effect.
