Description
The energy loss dE of 250 A MeV (∼52 GeV) bismuth ions in a 1 g/cm2 poly-crystalline gadolinium target was measured with the high-resolving magnetic spectrometer FRS at GSI as a function of the target temperature T at and above the Curie temperature T C of about 19 deg. C. After subtraction of effects due to thermal expansion of the target and due to a small asymmetric change of the charge state distribution, the relative energy-loss change (δE/dE)corr increases between 5 deg. C and 98 deg. C from 0 to 1.1(5) x 10-3. Between 13 deg. C and 15 deg. C a sharp increase by 0.26(3) x 10-3 is observed
