Magnetisation measurements in ultra-high magnetic fields produced by a single-turn coil system

Abstract
A technique has been developed for measuring magnetisation in very high magnetic fields (up to 90 T) produced by single-turn coils. The system is applied for measurements of high-field magnetisation of magnetic substances in a wide temperature range from room temperature down to 4.2 K. In a simple magnetic system, the one-dimensional Ising antiferromagnet CsCoCl3, the magnetisation curve was successfully obtained up to 90 T including a stepwise change around 40T at 4.2 K.
