NMR/NQR study of the quadrupole orders in binary uranium-palladium intermetallic compound

UPd$$_3$$ shows the successive quadrupole orders at $$T_{rm Q0}=7.5$$ K, $$T_{rm Q1}=6.8$$ K and $$T_{rm Q2}=4.5$$ K. The phase transition at $$T_{rm Q0}$$ comes from the (1/2,0,1/2)-type quadrupole orders on quasi-cubic uranium-sublattice. On the other hand, the quadrupole states below $$T_{rm Q1}$$ are still controversial; while the Polarized Neutron Diffraction suggested the triple-$$q$$ structure, the Resonant X-ray Scattering assumed the canted quadrupole order. In addition, below $$T_{rm Q2}$$, an antiferromagnetic order has been suggested, but the magnetic structure and so on are not still identified. To investigate the local symmetry of the quadruple order in UPd$$_3$$, we tried the nuclear quadrupole resonance, and we succeeded to find the first spin-echo signals from the UPd$$_3$$ probed by $$^{105}$$Pd nuclei. In this paper, we report the nuclear properties of $$^{105}$$Pd isotope and discuss the characteristics of the quadrupole orders emerging in each temperature phases.
