This paper reports that the study results of the stabilization energy dependence of the temperature for RCo 5(R=Pr,Nd,Tb,Dy,Ho) and R 2Co 17(R=Er,Tm,Yb) compounds,which was studied again by us after J.E.Greedan & V.U.S.Rao and For RCo 5(R=Pr,Nd,Tb,Dy,Ho)compounds was defferent from the results of J.E.Greedan and V.U.S.Rao.|E st(T)| monotonously decreases with increase in temperature.Moreover,at a higher temperature,as the temperature rises,|E st(T)| drops more drastically than the results obtained by J.E.Greedan and V.U.S.Rao.The shape of curves describing |E st(T)| for R 2Co 17-Th 2Ni 17(I) and (Ⅱ)(R=Er,Tm,Yb) is similar with that of RCo 5(R=Pr,Nd,Tb,Dy,Ho).Furthermore,|E st(T)| of R 2Co 17-Th 2Ni 17(R=Er,Tm,Yb) composed of that of R 2Co 17-Th 2Ni 17(I) and (Ⅱ)(R=Er,Tm,Yb) is still much defferent from the results obtained by J.E.Greedan and V.U.S.Rao.The paper also elaborately illustrate the numerical method in deriving these consequence.
