近年来,我们已经利用高温高压方法合成了若干双稀土化合物和固溶体,并且测定了它们的一些物理性能。这些对发展稀土固体物理学都有着重要的意义。 由于双稀土固溶体中的4f电子的局域程度较大,所以由两种稀土离子相互作用引起的
In recent years, we have synthesized several double rare earth compounds and solid solutions by using high temperature and high pressure methods, and measured some of their physical properties. These are of great significance to the development of rare earth solid state physics. Due to the large local extent of 4f electrons in the double rare earth solid solution, the interaction between the two rare earth ions
