Abstract: The magnetization M(H), the spontaneous magnetization M(T), and the cone angle θc (T) between the easy direction of magnetization and the c axis of rare earth compounds Y1-xPrxCo5 and Y1-xSmxCo5 are studied by means of the improved Hamiltonian.The calculated results are in agreement with the experimental M(H),M(T) and θc(T), and the calculated result of second order crystal field parameter A20 for the compounds Y1-xPrxCo5 is improved.
