| Abstract | Phys. Rev. B 86, 184416 (2012) We report magnetization and magnetoresistivity measurements on the
isostructural ferromagnetic superconductors UCoGe and URhGe in magnetic fields
up to 60 T and temperatures from 1.5 to 80 K. At low-temperature, a moment
polarization in UCoGe in a field $\mu_0\mathbf{H}\parallel\mathbf{b}$ of around
50 T leads to well-defined anomalies in both magnetization and
magnetoresistivity. These anomalies vanish in temperatures higher than 30-40 K,
where maxima in the magnetic susceptibility and the field-induced variation of
the magnetoresistivity are found. A comparison is made between UCoGe and URhGe,
where a moment reorientation in a magnetic field
$\mu_0\mathbf{H}\parallel\mathbf{b}$ of 12 T leads to field-induced reentrant
superconductivity. |
