Comprehensive analyses of the 115In-NQR spectra employing a magnetic dipolar model and a transferred hyperfine model are performed to determine the magnetic structures of Ce3PtIn11. Based on this analysis, we confirmed that the magnetic moment at the

T’-La1.8Eu0.2CuO4–y F y (0 ≤ y ≥ 0.125) was measured by 63,6BCu and 139La NMR. This material is an electron-doped high-Tc cuprate superconductor which has Nd2CuO4-type structure (so-called T’-structure). The nuclear spin-lattice relaxation

We report ${}^{51}\mathrm{V}$ NMR measurements in ${\ensuremath{\alpha}}^{\ensuremath{'}}$-${\mathrm{NaV}}_{2}{\mathrm{O}}_{5}$, which has been considered as a spin-Peierls (SP) system. Above the transition temperature ${T}_{\mathrm{C}},$ only one se

51 V NMR measurements in the uniform state of NaV 2 O 5 are presented. The NMR shift and the electrical field gradient (EFG) were measured at the tetravalent V sites. Observed anisotropy of the NMR shift and the EFG indicates that the d x y -like orb

The anisotropies of the Knight shift and the nuclear spin-lattice relaxation time ( T 1 ) at the Sn sites have been measured up to 300 K with a magnetically aligned powder sample of CeNiSn. In contrast to the results of previous neutron scattering me

The magnetic susceptibility and the Cu and Si Knight shifts have been measured in CeCu 2 Si 2 . The transferred hyperfine couplings at both the sites are strongly temperature-dependent and noticeably anisotropic at low temperatures. The negative hype

The temperature dependence and the anisotropy of the magnetic susceptibility and the Knight shifts have been measured in PrCu 2 Si 2 and GdCu 2 Si 2 with magnetically aligned powder samples. For GdCu 2 Si 2 , the isotropic s-f exchange model provides

NMR and NQR measurements have been made for Pauli paramagnetic UNi 2 Ga. The temperature dependence of the Knight shift and the nuclear relaxation rate 1/ T 1 at the Ga sites has been measured between 4.2 K and 290 K. Fermi liquid behavior, that is,

The 121 Sb Knight shift and the 121,123 Sb nuclear spin-lattice relaxation time T 1 in U 3 Ni 3 Sb 4 have been measured. In the temperature range between 25 and 250 K, 1/ T 1 , which has been measured by nuclear quadrupole resonance (NQR), follows an
