Research Abstract

A new furnace with a transparent glass heater has been developed for diamagnetic susceptibility measurements using a magnetic levitation technique. This furnace allows sensitive and contactless measurements of the susceptibility change and observation of containerless melting and solidification processes up to 300°C, because it is easy to observe a sample from outside of the furnace during heating in high magnetic fields.
