| Abstract: | The ternary CeFe 4Al 8 Compound has been synthesized by arc melting and its structure has been determined from X ray powder diffraction analysis. The magnetic susceptibilities of the compound have been measured in the temperature range from 77 to 302 K. Mssbauer spectrum measurment has been performed for the compound at room temperature. The results show that the compound obeys the Curie Weiss low down to near its Neel temperature 127 K and has an effective magneton number of 6 97 and iron average magneton number p eff =1 21. |
