In materials with correlated disorder (i.e. not completely random nor completely ordered), new physics and functionalities can occur. Correlated disorder can be treated...

The experimental realization of a Kitaev model on the honeycomb lattice has been a major topic in a condensed matter physics, because the model uniquely provides exactly...

Yttrium Iron Garnet (YIG) is a material with extremely wide ranging applications. It is a ferrimagnetic spinel with the narrowest ferromagnetic resonance linewidth of any known...

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...

In recent years, there has been a great interest in quantum spin liquid (QSL). The QSL state is characterized by no conventional order parameter associated with a broken...

Understanding the electronic anisotropic state at a temperature associated with the nematic phase is unresolved problems in iron pnictides. Although many experiments focus on...

Graphene is the single layer of honeycomb-shaped carbon network, for which 2010 Nobel Prize in Physics was awarded thanks to its novel electronic properties. One of such...

In a magnetic Weyl semimetal (WSM) with broken time-reversal symmetry, large intrinsic anomalous Hall effect is expected if the Weyl nodes are close to Fermi energy, which...

The LaFe13-xSix system (x<1.6) has a first order ferromagnetic, FM, to paramagnetic, PM, transition that is tunable in magnetic field, ending at a (tri)critical point (Hcrit,...

Heisenberg antiferromagnetic (HAF) S = ½ chains are famous for their gapless magnetic excitation spectrum. Interestingly, in SrCuO2 and Sr2CuO3, which are some of the best...

With this experiment we aim to investigate the role of spin orbit coupling (SOC) in 4d transition metal oxides.In previous inelastic neutron scattering experiments on the parent...

Test of the NIMS low temperature pressure cell on WISH.

The strontium iridate Sr2IrO4 has recently received a special attention because of its closeresemblance to undoped high-Tc cuprate in terms of structural, electronic, and...

Erbium iron garnet is a technologically important material with potential use in quantum computing. The predicted presence of a magnetic resonance and an optically active erbium...

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)...

The electronic dispersion of "Dirac" materials such as graphene and topological insulators is linear, resulting in a variety of peculiar electronic properties. In graphene and...

Linarite is a natural mineral which displays a rich and complex phase diagram in applied fields up to 10T for temperatures below 2.8K. A frustrated J1-J2 chain system, linarite...

Magnetic quantum critical points (QCPs) in strongly correlated electron systems, i.e. continuous phase transitions at absolute zero temperature, considerably attract both...

Both 1D physics (dimensional frustration) and geometric frustration offer ways of achieving unusual quantum ground states that defy the usual tendency for systems to order at...

We propose to perform neutron diffraction experiments under high-pressure on a frustrated antiferromagnet CuFeO2 using WISH in combination with hybrid-anvil-type high-pressure...
