| Research Abstract |
In order to investigate whether alloy melts of iron and platinum elements show ferromagnetic or not, the melts were undecooled by a electromagnetic levitation method under a strong static magnetic field. The newly-developed setup makes it possible to measure magnetization of the deeply undercooled melts based on a non-contact high-precision optical technique. In the result, undercooled Co_<80>Pd_<20> melt near its Curie point showed a sharp rise of magnetization. However, a ferromagnetic transition of the melt was not measured because of rapid solidification of the melt at a deeper undercooling condition.
