Title: Magnetic properties of nano-crystalline Fe-Cr alloys prepared by mechanical alloying

Abstract

Fe-Cr powdered alloys synthesized via mechanical attrition have been examined by magnetization and {sup 57}Fe Moessbauer spectroscopy. Moessbauer studies reveal that Fe{sub 1{minus}x}Cr{sub x} becomes paramagnetic for x {ge} 0.46 after 100 h milling. Magnetization results suggest that a significant reduction of Fe magnetic moment occurs in the nano-crystalline Fe{sub 1{minus}x}Cr{sub x} alloys. Curie temperature for x = 0.46 and 0.69 lies below liquid N{sub 2} and liquid He temperature, respectively.
