由草酸盐先驱物制备尖晶石型化合物MCo_2O_4

THE WIGNER RACAH ALGEBRA FOR GROUP CHAIN SU(2)D ∞D nC n Ⅳ. Reduced V Coefficents, 3 jΓP Symbol and Their Microcomputer Programs

报道了用草酸盐先驱物制备尖晶石型化合物ＭＣｏ２Ｏ４（Ｍ＝Ｍｎ，Ｃｕ，Ｚｎ，Ｃｄ，Ｎｉ，Ｍｇ）的方法．用热重、Ｘ射线粉末衍射和ＩＲ光谱证实了尖晶石型化合物ＭＣｏ２Ｏ４的形成；由扫描电镜测得最终产品的颗粒尺寸为１～１０μｍ．

In present paper the reduced V coefficients and related 3 jΓ, 3 ΓP and 3 jΓP symbols of the group chain SU(2)D ∞D nC n have been discussed by using the standardized basis vectors.The formulas of calculating these coupling coefficients have been given in Wigner Racah algebra of the group chain.The program design of these formulas is completed by using FORTRAN 77 Language.These programs are suitable for arbitrary group D nC n and are run in IBM PC/XT computer.
