The debate whether interband or intraband scattering is crucial for Fe-based superconductors is not settled down yet. Investigation a system with completely missing electron...

By introducing transvers terms in the effective spin-1/2 Hamiltonian on the pyrochlore lattice, the quantum spin ice (QSI) state, a special quantum spin liquid whose emergent...

Rare-earth frustrated magnets have attracted great interest because they can form rather complex ground states such as hidden order phases, the order parameters of which cannot...

We have investigated the magnetic structure and crystal field excitations (CEF) of CeT2Al10 (T=Os and Ru). The observed magnetic moment along the c-axis does not agree with that...

UPd3 exhibits four antiferroquadrupolar (AFQ) ordered phases below T0=7.6K. We have determined their order parameters using resonant x-ray diffraction. UPd3 has the dhcp crystal...

Ba4Mn3O10 and Sr4Mn3O10 crystallize in an orthorhombic crystal structure consisting of corrugated layers containing Mn3O12 polydedra. The magnetic susceptibility of the...

La2O2M2OSe2 (M=Fe, Co, Mn) are layered Mott-insulating antiferromagnets with a potential to be a non-copper high-Tc superconductor. All compounds have shown unusual magnetic...

We have recently investigated a hybridization gap in Kondo systems using HET and several papers along with a review have been published. Our study shows a universal scaling...

Recently we have investigated the cubic compound PrRhSn3 using the dc and ac susceptibilities and the heat capacity. We found an evidence for the cluster-glass behavior with a...

The discovery of unconventional superconductivity (SC) in several heavy fermion (HF) compounds has attracted considerable attention. Recently we have investigated CeTSi3 (T=Rh...

Previous studies have pointed to a heavy-electron state in CePtSi with a strongly enhanced electronic specific heat. We have explored the heat capacity, susceptibility and...

Recently discovered tetragonal compounds CeRu2M2X (M=Al and Ga, X=B and C) provide new opportunity to investigate ferromagnetic and antiferromagnetic ordering in the same...

The nature of the ground state of the spin-1/2 kagome lattice antiferromagnet remains an important question. Cu(1,3-bdc) is a hybrid organometallic compound featuring S=1/2 Cu2+...

We propose to perform neutron scattering experiment in a new field of science, magnetic O2 molecule supercrystal realized in nanoporous compound. In our previous work on...
