The purpose of this paper is to determine by experiment whether Mn 11 Si 19 and Mn 4 Si 7 in their bulk states have a finite magnetic moment or not. Magnetisation measurements were carried out on these materials using both SQUID system and Kerr rotation system. The high quality samples were grown using the temperature gradient solution growth method. SQUID measurements revealed that Mn 11 Si 19 has finite magnetism while Mn 4 Si 7 does not in their bulk states. It was also confirmed that Mn 4 Si 7 became magnetic and Mn 11 Si 19 got to exhibit a distinctive hysteresis in their powdery state. The enhancement of magnetism implied that the surface of the samples was to a great extent linked to its magnetism. |
