W. Mexner et K. Heinemann, AN IMPROVED METHOD FOR RELAXATION MEASUREMENTS USING A FARADAY BALANCE, Review of scientific instruments, 64(11), 1993, pp. 3336-3337
Due to an eddy current-free sample holder of a high mass density, it i
s possible to investigate the magnetic relaxation of high temperature
superconductors at early times with a Faraday magnetometer. The experi
ments can be performed beginning after t0 almost-equal-to 1 s with a r
esolution of 10(-5) in the susceptibility.
