Abstract
The spin-polarized electron momentum distributions of the magnetic superconductor RuSr2GdCu2O8 in its various phases have been measured using the magnetic Compton scattering technique with elliptically polarized synchrotron radiation. A contribution to the spin moment from magnetically ordered Ru 4d electrons was seen with a large induced Gd 4f moment below 25 K. A small negatively polarized component is observed in the antiferromagnetic phase of the Gd sublattice, at 2 K. The momentum distribution of this was consistent with the existence of a Gd 5d electron moment anti-parallel with respect to the now ordered Gd 4f moment.
