Local spin dynamics in geometrically frustrated Mo pyrochlore antiferromagnet LuMoON
S. K. Dey, K. Ishida, H. Okabe +6
The magnetic ground state of oxynitride pyrochlore LuMoON, a candidate compound for the quantum spin liquid (, Mo), was studied by muon spin rotat…
First-Order Antiferromagnetic Transition and Novel Gapless Excitation in a 4f Zigzag Chain Compound YbCuS2
F. Hori, K. Kinjo, S. Kitagawa +3
We report on the 63/65Cu-nuclear magnetic resonance and nuclear quadrupole resonance (NQR) studies of trivalent Yb zigzag chain compound YbCuS2. Sharp NQR signals were observed in…
Quantum Criticality Based on Large Ising Spins: YbCoGe with New 1-2-4 Structure Type
K. Kitagawa, Y. Kishimoto, M. Iwatani +8
We present a new type of quantum critical material YbCoGe, having the largest quantum-critical pseudospin size ever. The YbCoGe-type structure is new, forms in the…
Spin dynamics in a structurally ordered non-Fermi liquid compound: YbRh_2Si_2
K. Ishida, D. E. MacLaughlin, O. O. Bernal +5
Muon spin relaxation (muSR) experiments have been carried out at low temperatures in the non-Fermi-liquid heavy-fermion compound YbRh_2Si_2. The longitudinal-field muSR relaxation…

We report the novel pressure() - temperature() phase diagram of antiferromagnetism and superconductivity in CeRhIn and CeIn revealed by the In nuclear-spin-la…
Pressure-induced anomalous magnetism and unconventional superconductivity in CeRhIn5 : 115In-NQR Study under Pressure
T. Mito, S. Kawasaki, G. -q. Zheng +6
We report In nuclear-quadrupole-resonance (NQR) measurements of the pressure()-induced superconductor CeRhIn in the antiferromagnetic (AF) and superconducting (SC) s…
Exotic Superconducting Phase in CeCu2Si2 Close to Antiferromagnetism : A Cu-NQR Study under Hydrostatic Pressure
Y. Kawasaki, K. Ishida, T. Mito +5
We report Cu nuclear-quadrupole-resonance results under pressure on a homogeneous CeCu2Si2 (Tc = 0.65 K) that revealed critical magnetic fluctuations at the border to an antiferrom…
Coexistence of Superconductivity and Antiferromagnetism in Heavy-Fermion Superconductor CeCu_{2}(Si_{1-x}Ge_{x})_{2} Probed by Cu-NQR --A Test Case for the SO(5) Theory--
Y. Kitaoka, K. Ishida, Y. Kawasaki +3
We report on the basis of Cu-NQR measurements that superconductivity (SC) and antiferromagnetism (AF) coexist on a microscopic level in CeCu_{2}(Si_{1-x}Ge_{x})_{2}, once a tiny am…
