Abstract
The new quasi-static high-field installation at the T.U. Wien is described. With a regulated power supply of 10 MW, field pulses up to 40 T with a pulse duration of 1 s can be obtained. Polar and bipolar field pulses are possible. Three working stations were established: (i) a high-temperature magnetometer which allows magnetization measurements between room temperature and 500°C in external fields of 35°T; (ii) a low-temperature system with a maximum field of 40 T which operates between 1.5 and 300 K. Magnetization measurements between 1.5 and 800 K in high external fields are possible. (iii) An additional room temperature test system for developing new measurement methods. The construction of the high temperature set-up is described and an example of an experiment is shown. First magnetostriction measurements on an anisotropic technical barium ferrite are shown. Possibilities to improve the signal-to-noise ratio for magnetization measurements are discussed.
