Photoinduced phase transition of coordinationally unsaturated d(9) metal centers within the thermal hysteresis of the spin exchange interaction

摘要

Diffraction evidence is presented that the structure of one-dimensional arrays of strained, coordinationally unsaturated d(9) pseudo-Jahn-Teller centers is affected by excitation of the LMCT bands within the hysteresis region of the low-temperature ferromagnetic-to-antiferromagnetic phase transition.
