Описаны условия синтеза и результаты экспериментального исследования кристаллической структуры и магнитных свойств нового магнитного соединения YbFeTi 2 O7. Методом рентгеновской дифракции установлено, что кристаллическая структура исследуемого образца описывается ромбической пространственной группой Pcnb с параметрами элементарной ячейки: a = 9.8115(1) ¦ ; b = 13.5106(2) ¦ ; c = 7.31302(9) ¦
In the low temperature region, a change in the magnetic state was detected in the new NaNiFe2(VO4)3 magnetic compound, confirmed by the results of experimental study by gamma resonance and magnetometry methods. The formation of disordered magnetism in multicomponent vanadate is facilitated by the features of the crystal structure, in which magnetically active cations occupy several crystallographically non-equivalent mixed positions with uneven filling with iron and nickel ions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
