Materials with large caloric effects offer the opportunity to replace current refrigeration technologies that require the compression of hazardous gases. Whilst magnetocaloric...

The intermetallic series RNiAl4 (R = rare earth) exhibit interesting low temperature magnetic behaviour including a variety of (in)commensurate magnetic phases and metamagnetic...

The microscopic origin of the zigzag magnetic ground state in a honeycomb lattice of the quasi-2D antiferromagnet Na2Co2TeO6 is debatable. The zigzag phase may occur due to (i)...

Recently, it has been suggested that the First Sharp Diffraction Peak (FSDP) in glasses arises from a quasi-periodicity of void spaces in the structure, that plays the role of...

The ferromagnetic transition Tc=41 K of CeIr3B2 is the second highest Tc recorded after CeRh3B2 in among Ce-based compounds makes it an interesting candidate to investigate...

Thermoelectric materials are increasingly attracting attention due to their potential for use in devices for waste heat energy recovery. Bismuth copper oxychalcogenides have...

Electronic nematic phase in iron-pnictide superconductors have been discovered in various systems by techniques such as resistivity, ARPES, magnetic torque and neutron...

Honeycomb magnets with strong spin-orbit coupling (SOC) are expect to produce exotic magnetic ground states as exemplified by d5 iridates with Jeff = 1/2 state. In d4 case, SOC...

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...

Weyl magnon in the chromium-based breathing pyrochlores is a recently predicted novel magnetic excitation state. Similar to its anolog, Weyl fermion in the electric systems,...

Oxide ion conductors are researched as electrolytes in solid oxide fuel cells. Yttria-stabilized zirconia is the currently used electrolyte in SOFCs, leading to high operating...

Special attention has been devoted to the honeycomb iridates (Na, Li)2IrO3, in which SOC, intrinsic geometric frustration, and other competing interactions favor a highly...

The series of spinel ferrites, RFe2O4 has attracted the community for the similar structural and physical properties of magnetite (Fe3O4). Analogous to Fe3O4, NiFe2O4 recently...

The rare-earth compound KYbSe2 provides a new chance for the study of frustrated magnets with strong SOC. It resembles YbMgGaO4 in many ways. Our susceptibility and specific...

CeIr3Si2 exhibits highly anisotropic bulk properties with two magnetic transitions at TN1 ~ 3.9 K and TN2 ~ 3.1 K. The overall CEF splitting of the J=5/2 ground multiplet of...

We recently observed a resonant spin excitation in Ba1-xKxFe2As2 (x=0.4), one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates...

Recently, a novel type of Bose-Einstein condensation (BEC) of spin-orbit excitons has been proposed in Mott insulator Ca2RuO4. In the recent INS study, we have observed...

A series of recent incoherent inelastic neutron scattering (INS) experiments on low-temperature D2+H2 and Ne+H2 mixtures have revealed pronounced deviations from the Gaussian...

Spin dynamics in multi-q noncoplanar ordered structures (e.g. skyrmion lattices) is an active topic of research. The cubic perovskite SrFeO3 has a variety of multiple-q magnetic...

In the last 25 years the highest blocking temperature TB achieved for the best performing molecular nanomagnets has only reached few K. The situation has recently changed...
