摘要

In this letter, an unpredictable change of magnetism-controlled lateral photovoltaic effect was observed in a well-designed Cu/SiO2/p-Si nonmagnetic structure, which performs better than that in Cu/SiO2/n-Si. When a vertical magnetic flux density changes from 0 to 0.55 T, maximum value of lateral photovoltage drops from 84.3to 31.2 mv. The sensitivity changes 63% and the change rate reaches 290 mv...
