摘要：

We studied the external magnetic field effects on the photoinduced magnetization of a cobalt iron cyanide, K0.4Co1.3[Fe(CN)(6)]. 5H(2)O. Photoinduced magnetization value was increased ca. 20 % at maximum under the magnetic field of 50000 G at 5 K. In addition, in the ferrimagnetic region (T < T-c = 26 K), the external magnetic field accelerated the rate of photoinduced spin generation. Those data suggest that external magnetic field increases magnetic interaction between the excited state and spin clusters.
