摘要：
In the present paper the effect of photoinduced charge carriers of the two-magnon scattering spectrum of YBa2Cu3O7-delta is studied. The band intensity of two-magnon scattering is found to decrease upon laser radiation. Photoinduced variations in Raman spectra are long-lived: at room temperature the sample relaxation time to an unexposed state is about 40 hours. Possible mechanisms of the phenomenon observed are discussed.
