Outline of Final Research Achievements

The Gd-Hg, Co-Sn and Mn-Bi alloys were prepared to study the physical properties in order to realize the magnetic phase transition of supercooled liquid metal. The magnetic properties in the sample were observed by magnetic measurement before heating and after cooling under a magnetic field. Some anomaly shapes were recognized for the Mn10Bi90 alloy. This unevenness could indicate appear of magnetism in the supercooleing liquid.
