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…
Change of superconducting character in UTe2induced by magnetic field
K. Kinjo, H. Fujibayashi, S. Kitagawa +13
UTe2 is a recently discovered spin-triplet superconductor. One of the characteristic features of UTe2 is a magnetic field (H)-boosted superconductivity above 16 T when H is applied…
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…
Pairing interaction in superconducting UCoGe tunable by magnetic field
K. Ishida, S. Matsuzaki, M. Manago +5
The mechanism of unconventional superconductivity, such as high-temperature-cuprate, Fe-based, and heavy-fermion superconductors, has been studied as a central issue in condensed-m…
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…
