摘要：

Pressure and photoirradiation effects on the structural properties were investigated for a transition metal cyanide, RbMn[Fe(CN)(6)], with perovskitelike structure by means of high-angle resolved synchrotron-radiation x-ray powder diffraction. We have found that (1) photoirradiation by a 532-nm pulse laser at 91 K and (2) application of hydrostatic pressure to about 2 GPa at 300 K change the system from the tetragonal low-temperature phase (I (4) over bar m2; Z=2) to a metastable state with different crystal symmetry (P (4) over bar n2; Z=2). We discuss the difference between the photoinduced and pressure-induced processes and suggest possible origin for the photoinduced demagnetization.
