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...

This proposal was submitted on MERLIN (RB1010206) and beam time was allocated on MARI. We have carried out low energy measurements on MARI and found a clear evidence of the spin...

We have recently succeeded in measuring the excitation spectrum of charge doped cuprate chains with a 90 degree Cu-O-Cu bonding geometry. This study resolved a long standing...

Neutron spin resonance mode is a common feature in different classes of magnetic superconductors; nonetheless, the microscopic origin of the mode is still unclear. In general,...

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...

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

We aim to determine the ligand field parameters of the [HoPc2]¿ complex belonging to the family of lanthanide double decker (Ln=Dy3+,Ho3+,Tb3+) single-molecule magnets (SMM),...

Pr2Hf2O7 is a potential quantum spin ice compound. Compared to the classical spin ice ions Ho3+ and Dy3+, Pr3+ has weaker Ising anisotropy and significant XY terms leading to...

Dynamics of multicomponent mixtures such as polymer blends are typically studied with QENS and deuterium labelling. Difficulties arise in the data analysis if the coherent...

The growth in both global demand for energy and fossil-fuel related environmental issues drive research on alternative fuel sources. Solid oxide fuel cells, which can operate on...

We propose to measure the magnetic excitations in malachite, a mineral that contains S=1/2 alternating chains with an alternation parameter of J'/J=0.5, just in the middle...

We propose to investigate the magnetic excitation spectra in the three accessible magnetic ordered phases of the quasi-1D S-1/2 Ising-like antiferromagnet SrCo2V2O8 by single...

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...

The ordered double perovskite Sr2CuWO6 is a quasi-two dimensional J1/J2 frustrated square lattice model antiferromagnet. The divalent Cu carries S = 1/2 while the W (VI) is 4d0....

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 non conventional d-wave superconductivity in Heavy Fermion compounds seems to be triggered by spin fluctuations, which is in strong contrast to conventional...

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

The heat capacity and neutron powder diffraction measurements of the double perovskites La2NaB′O6 (B = Ru5+, Os5+) with S=3/2 on the B¿ reveal an incommensurate magnetic...

The experiment is aimed to unravel the diffusion mechanism of hydrogen in Callovo-Oxfordian clays, which are candidates to be used as backfill material in long term geological...
