In ionic clusters the polarization depends on the dynamics of charge delocalization. The polarization follows the charge motion when the characteristic time of motion is much longer than the polarization time (adiabatic polarization ). For the opposite case (diabatic polarization), the polarization
Spectacular oxygen isotope ( 18 O) enhancement of chargeordering temperatures is reported in manganese perovskites Nd0.5Sr0.5MnO3 and La0.5Ca0.5MnO3. The isotope shift of charge-ordering temperatures was found to increase with increasing average radius of the A-site cations, 1rA2 and A-site size dis
