Uniaxial pressure effect in FeTe
Superconductivity in iron-based materials occurs in close proximity to a long-range ordered magnetic phase. In the iron pnictides, uniaxial pressure shifts the magnetic ordering... -
Low-dimensional glasses: Effect of occupational site disorder in the excess o...
The present scientific case concerns a glass-forming system with even less degrees of freedom, namely the occupational disorder of high-temperature phase (I, P21/c) of... -
The role of zero-point fluctuations in a quantum-disordered spin-dimer compound
Recently a great deal of theoretical and experimental interest has been directed at a class of magnetic materials which undergo phase transitions at zero temperature. These... -
Dispersionless spin waves and field-induced magnetic order in Gd3Al5O12
Gd3Ga5O12 (GGG) is the archetypal frustrated magnet with unusual short-range order and magnetic excitations. Recently we have found that the dominant contribution to INS in GGG... -
Phonon Anomalies in YMnO3 at High Temperature
The reported structural phase transition in YMnO3 from P63cm to P63/mmc space group occurs at 1258 ±14 K. For low temperature phase (space group P63cm) the phonon modes are... -
Neutron scattering study on the honeycomb Heisenberg-Kitaev magnet alpha-RuCl3
The experimental realization of a Heisenberg-Kitaev model on the honeycomb lattice has been a major topic in a condensed matter physics, because the model predict a novel... -
Coating dependance of the phonon density of states in LiFePO4 nanoparticles
LiFePO4 (LFP) is a commercially used Li ion battery material for high power applications. Particle shape and surface play an important role in the Li diffusion and thus the...
