| Popis: | The orbital order-disorder transition temperature (T_OO) versus tolerance factor (t) plot switches from monotonic to non-monotonic beyond a doping level (x) ~ 10 atom% in a family of R(1-x)A(x)MnO3 systems(R = La, Pr, Nd; A = Ca, Sr; x = 0.0-0.2). T_OO reaches maximum at a 'doping-dependent' critical tolerance factor t_C(x) (for 0.1 |
