| Popis: | 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. The prominent fall in the magnetization value at around 50 K observed in ZFCM curve reveals the existence of a sharp transition from a ferromagnetic state to a glassy ferromagnetic state. The presence of glassy ferromagnetism at low temperature is confirmed from the M-H curve recorded at 5 K. |
