Large orbital magnetic moment and its quenching in the itinerant uranium intermetallic compoundsUTGa5(T=Ni,Pd,Pt)

The crystal structure, lattice strain due to the antiferromagnetic ordering, and magnetic form factor in the itinerant $5f$ compounds $\mathrm{U}T{\mathrm{Ga}}_{5}(T=\mathrm{N}\mathrm{i},\mathrm{}\mathrm{P}\mathrm{d},\mathrm{}\mathrm{Pt})$ have been studied by neutron scattering. High-resolution powder diffraction revealed that the tetragonality of the U-Ga layers increases down to the series of the transition metal element T. The integrated intensities of the antiferromagnetic reflections can b
