Opis:: By means of neutron diffraction on a hexagonal UIrAl single crystal we find that this system orders ferromagnetically at low temperatures with magnetic moments of 0.93 (10) $μ_B$ aligned along the c axis. The Curie temperature $T_C$ = 65 (5) K determined from the diffraction experiment is in good agreement with bulk magnetic measurements.

Opis:: UCoGe is an archetype of coexisting weak itinerant 5f-electron ferromagnetism ($T_{C}$~3 K, $μ_{s}$=$0.03μ_{B}$/f.u.) and superconductivity ($T_{SC}$~ 0.6 K) at ambient pressure. The Ru substitution for Co leads to an initial sharp increase of the $T_{C}$ up to the maximum of $T_{C}$=8.5 K for x=0.12, increase of spontaneous magnetic moment and suppression of superconductivity. We have grown the $UCo_{0.88}Ru_{0.12}Ge$ single crystal and studied magnetization along the principal crystallographic axes. To see the microscopic background of these findings we performed a polarized neutron diffraction experiment on D3 diffractometer in ILL. We have found that the Co and U moments are parallel in $UCo_{0.88}Ru_{0.12}Ge$, in contrast to the antiparallel configuration in UCoGe. This is probably the reason of the spontaneous magnetization increase with Ru doping.
