Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ОКСИД МАРГАНЦА -- ПЕРОВСКИТЫ -- МАГНИТНЫЕ СВОЙСТВА Аннотация: New compounds Pr1.5Sr1.5CuMnO 6.5 and Nd1.5Sr1.5CuMnO6.5 with an An+1BnO3n+1(n= 2) structure have been synthesized. The magnetic susceptibility of both compounds follows the Curie–Weiss law above 300 K. Bellow this temperature, ESR detects the local ferromagnetic ordering of magnetic ion pairs Полный текст |
