Structural and magnetic properties of bulk alloys and aerosol nanoparticles in the Fe100−xCrx system

The results of comparative analysis of structural and magnetic measurements in the Fe100−xCrx (x = 2.4–80.0) system for bulk alloys and for aerosol nanoparticles are presented. The concentration dependencies of saturation magnetization and coercivity are given. Temperature dependencies of magnetization, M(T), for some bulk alloys and nanoparticles have been obtained. Depending on the Cr content, a different character of the M(T) irreversibilities in FeCr nanoparticles was observed.
