초록

In this experiment, flux method was applied for preparing ferroxplana at low temperature, The common salt was used as a flux. The mole ratio of flux to Zn$_2$Y was varied with 0, 6.5, 13, 26 and 52 in dry ball-mixing. Zn$_2$Y was obtained after heat treatment of the mixed powder. Crystallization, particle morphology and magnetic properties of the prepared powder were investigated using XRD, VSM and SEM. The ferroxplana powder of 2-4 ${\mu}{\textrm}{m}$ was obtained with the mole ratio 26 by heat treating at the temperature of 110$0^{\circ}C$. The coercivity(H$_{c}$) and saturation magnetization(M$_{s}$) of the ferroxplana were 282Oe and 64.5emu/g, respectively.y.y.
