High-field moment polarization in the ferromagnetic superconductor UCoGe; similarities with the URhGe-case

Institut fu¨r Festko¨rperphysik, Karlsruher Institut fu¨r Technologie, 76021 Karlsruhe, Germany.(Dated: January 9, 2014)We report magnetization and magnetoresistivity measurements on the isostructural ferromagneticsuperconductors UCoGe and URhGe in magnetic fields up to 60 T and temperatures from 1.5 to80 K. At low-temperature, a moment polarization in UCoGe in a field µ
