| Abstract: | The temperature dependence of magnetization of amorphous Fe 77 Cr 13 Zr 10 alloy have been measured in the temperation range 1.5 to 300K.The results indicate:it is affected by the values of magenetic-field and there is a spin-glass phase in low temperature.The temperature dependence of spontaneous magnetiation obeys the Bloch's T 3/2 law.The spin-wave stiffness constant D has been calculated. |
