一、引言稀土硫属、氮属化合物是指稀土与第ⅥA及ⅤA族元素所形成的二元及多元化合物。自五十年代末制备出这类化合物以来,特別是在1961年发现了EuO在低温下显示强磁,引起了很大注意,随后迅速开展了有关稀土硫属、氮属化合物的組成、性质、结构的研究。这类化合物具有某些特异性质,集中表现在磁性、半导体性及耐高温性等方面,例如铕的硫属化合物是磁性与半导体性兼备的磁性半导体;钐的硫属化合物是高温半导体,按其性质可望制成高温的
I. Introduction Rare earth chalcogenide, nitrogen compounds refers to the rare earth and the â ... ¢ A and VA elements formed by the binary and multiple compounds. Since the late 1950s, such compounds have been produced, and in particular, it was discovered in 1961 that EuO showed ferromagnetism at a low temperature, attracting a great deal of attention. Subsequently, the composition and properties of rare earth chalcogenides, nitrogen compounds, Structural research. Such compounds have certain specific properties, focusing on the magnetic, semiconducting and high temperature resistance, for example, europium chalcogenide is a magnetic and semiconducting magnetic semiconductor; samarium chalcogenide is a high-temperature semiconductor, according to its Nature is expected to make high temperature
