Austromag - a new multipurpose quasi-static high-field facility

The new quasi-static high-held installation at the T.U. Wien is described. With a regulated power supply of 10 MW, field pulses up to 40T with a pulse duration of Is can be obtained. Polar and bipolar held pulses are possible . Three working stations were established: (i) a high-temperature magnetome ter which allows magnetization measurements between room temperature and 50 0 degreesC in external fields of 35 degreesT; (ii) a low-temperature system with a maximum held of 40T which operates between 1.5 and 300 K. Magnetiza tion measurements between 1.5 and 800 K in high external fields are possibl e. (iii) An additional room temperature test system for developing new meas urement methods. The construction of the high temperature set-up is describ ed and an example of an experiment is shown. First magnetostriction measure ments on an anisotropic technical barium ferrite are shown. Possibilities t o improve the signal-to-noise ratio for magnetization measurements are disc ussed. (C) 2001 Elsevier Science B.V. All rights reserved.
