概要
- 論文の詳細を見る
Structural and magnetic properties have been investigated for half-doped single-layer manganites RE_<0.5>Sr_<1.5>MnO_4 [RE=La, (La, Pr), Pr, Nd, Sm, and Eu]. Analyses of electron diffraction and ac susceptibility measurements have revealed that the long-range charge-orbital ordering (CO-OO) state as observed in La_<0.5>Sr_<1.5>MnO_4 is suppressed for the other materials: the CO-OO transition temperature, as well as the correlation length decreases with a decrease in the cation size of RE. Such a short-range CO-OO state shows a spin-glass behavior at low temperatures. A new electronic phase diagram is established with quenched disorder as the control parameter.
