Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): СЛОИСТЫЕ ОКСИДЫ -- МАГНИТНЫЕ СВОЙСТВА Аннотация: A new oxide phase La1.5Sr1.5Mn1.25Ni0.75O6.67 ± 0.05, a member of the An + 1BnO3n + 1 (n = 2) Raddlesden–Popper homologue series, was synthesized, and its structure and magnetic properties characterized. Magnetic anomalies associated with the competition between antiferromagnetic and ferromagnetic orders are observed in the range of the temperatures studied (2–400 K). The ESR spectra of the compound feature the constriction of a magnetic signal and a shift toward g(Mn4+) Полный текст |
