Investigation of a spin-resonance in unconventional superconductor YFe2Ge2
In the layered iron-based superconductor YFe2Ge2, a high Sommerfeld ratio of order 100 mJ/mol K^2 and a T^3/2 temperature dependence of the electrical resistivity at low... -
Non-magnetic impurities in a strong-leg spin ladder
Th S = ½ AF spin ladder is one of the most important models in quantum magnetism. While its properties throughout the (H,T)-phase diagram may be considered to be well understood... -
Spin exchange interactions and fractionalized spin excitations in the geometr...
The recently discovered new triangular lattice QSL candidate YbMgGaO4 has attracted great interest on rare earth frustrated magnets. Another triangular lattice rare earth... -

Quantum critical E/T scaling of the dynamic susceptibility in Sr3Ru2O7
Spin fluctuations of materials close to a quantum critical point (QCP) exhibit anomalous behaviors. Sr3Ru2O7 has been shown to exhibit field-induced spin density wave (SDW)... -
Commensurate to incommensurate transition in triangular antiferromagnet PdCrO...
We propose to study an effect of uniaxial pressure on a magnetic structure of triangular antiferromagnet PdCrO2. The experiment will mark a technical milestone in development of...
