Magnetic properties of nanocrystalline beta SiC

Magnetic properties of nanocrystalline beta SiC

Four-hour ball-milled beta-SIC product synthesized by the thermal plasma technique shows room temperature ferromagnetism. The semi-lambda signature of the field-cooled magnetization (FCM) and zero field-cooled magnetization (ZFCM) curves suggest the possible signature of a glassy ferromagnetism state in the sample.
