Magnetic ordering in relaxation processes from photoinduced magnetic state in Prussian blue analogs

Abstract: We study magnetic ordering in non-equilibrium processes in temperature cycling where first the photoinduced saturated magnetic ordered state is prepared, and then the system is warmed up to a certain temperature (say ) and it is cooled down to the initial temperature. Using a generalized model which describes both spin-crossover transition and magnetic transition, we show that depending on the value of , the critical temperature of magnetization and its saturated value change, which reproduces qualitatively the experimental results of magnetic ordering. It is found that the properties of dilution of magnetic sites affect the magnetic ordering. [Copyright &y& Elsevier]
