Abstract

A magnetic tuning of the photovoltaic effect is demonstrated for the Schottky junction formed by a ferromagnetic (FM) layer and silicon. Obvious anisotropic magnetic photovoltaic effects (AMV) are gained not only in the FM layer but also in the Si substrate though the latter is non-magnetic. Key factors determining the AMV of Si are identified.

Keywords: Schottky junctions; anisotropic magnetic photovoltage; magnetic tuning; silicon.
