Advance of the precise measurement of diamagnetic susceptibility by using a magnetic levitation technique and its application for materials processing

利用磁悬浮技术研制了一种新型的带有透明玻璃加热器的电炉，用于测量抗磁化率。该电炉可对磁化率变化进行灵敏的非接触式测量，并可观察高达300°C的无容器熔化和凝固过程，因为在强磁场加热过程中，很容易从炉外观察样品。

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.
