本文研究了有机超导体κ-（BEDT-TTF）_2Cu [N（CN）_2]Br和β-（BEDT-TTF）_2I_3（BEDT-TTF =双（亚乙基二硫代）四硫富瓦烯）的磁化率的光辐射效应，并报道了它们的电导率的光响应。用连续可见光照射时，源于迈斯纳效应的抗磁化率降低，表明超导体体积百分比随光照射而降低。这些结果与用脉冲激光测量电导率的时间分辨光响应结果一致。
Photoirradiation effects on magnetic susceptibility are studied in organic superconductors of κ-(BEDT-TTF)2Cu[N(CN)2]Br and β-(BEDT-TTF)2I3(BEDT-TTF = bis(ethylenedithio)tetrathiafulvalene), for which we have reported photoresponses of the electrical conductivity elsewhere. With photoirradiation by cw visible laser light, the diamagnetic susceptibility originating from Meissner effect is reduced, indicating that the percentage of superconducting volume decreases with photoirradiation. These results agree with the ones of the time-resolved photoresponse measurements of the electrical conductivity using pulsed laser light.
