Crystal field and spin-wave excitations in the quasi-2D honeycomb zigzag anti...
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)... -
Incommensurate-commensurate phase transitions in K2SeO4
Materials with incommensurate structures often show exotic properties (such as charge density waves). The development of reliable and efficient refinement techniques for such... -
Search for Weyl Magnon in LiGaCr4O8
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,... -
Spin wave investigation in brownmillerite oxygen deficient perovskite Ca2Fe2O5
The Dzyaloshinskii-Moriya interaction is thought to be responsible for the stabilization of weak ferromagnetism or magnetic spiral states in a number of diverse systems. An... -
Revising the onset of anharmonicity in proteins
Our previous INS studies of ¿dry¿/hydrated apoferritin show that the hydrated protein undergoes a dynamical transition, Td, at 200K. Such behavior, first modeled by Doster et al... -
Phase Diagram of Ba1-xKxFe2As2
In the new class of iron pnictide superconductors, there is evidence of phase coexistence close to the phase boundary between the SDW and superconducting order produced by hole... -
QENS Studies of Diffusion of NH3 Molecules in Porous MOF Materials
The development of new porous metal-organic frameworks (MOFs) is receiving considerable attention worldwide owing to their potential for gas storage, separation, and... -
Neutron scattering investigation of Lithium diffusion mechanism in the Li-ion...
The compound LixCoO2 has attracted lots of attention in the recent years because of its application as cathodes in Li-ion batteries. The diffusion pathway of Li- ions within a... -
Local structure, dynamics and magnetism of the phases of cobalt imidazolate
This proposal concerns the metal-organic framework (MOF), cobalt imidazolate. Imidazole (im) is a small, flat organic molecule that forms slightly bent metal-im-metal linkages,... -
QENS Study of Proton Conducting Metal-Organic Framework Materials
The development of new functional metal-organic frameworks (MOFs) is receiving considerable attention worldwide owing to their potential for gas storage, ionic conductivity, and... -
Neutron diffraction and inelastic neutron scattering study on NdT2Al10 (T= Ru...
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... -
Investigation of diffusion of branched alkanes in ZSM5
The diffusion coefficients of monobranched and dibranched (methyl)hexane and octane in industrially important zeolite ZSM5 will be measured along with their straight chain... -
Excitations in an orbitally dimerized spin S=1 honeycomb antiferromagnet
Ru4+ ions in Li2RuO3 are on a bipartite lattice and have an orbital degeneracy. The four electrons of the magnetic Ru4+ ions in the threefold-orbitally degenerate t2g manifold... -
Quantum State Manipulation in PTFE.
Discrete energy level form in quantum mechanical systems and if carefully measured the population density of the levels can be probed and manipulated. The consequence of this... -
Investigation of a frustrated quantum magnet with novel interaction scheme
SrCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu ions that are coupled into network of isolated triangles,a highly frustrated hyperkagome lattice consisting of... -
Phonon Dispersion in the Organic Ferroelectric Croconic Acid
Organic ferroelectrics are important materials because of their technological applications in low-cost non-volatile memory elements. Single-crystal croconic acid (C5O5H2) is the... -
Proton diffusion in lithium imide: a quasi-elastic neutron scattering study
Li_2NH has been recently considered for H_2 storage applications. However, its low-T crystal structure is still controversial, with at least 6 options compatible with the... -
Structure and magnetic order in chemically modified schafarzikites
Schafarzikite minerals are structurally interesting in having 1-D chains of edge-linked transition metal octahedra. This experiment aims to determine the cause of the... -
Neutron scattering study of a triangular-lattice NaYbO2: a quantum spin liqui...
The Quantum spin liquid (QSL) state continues to fascinate the condensed matter community. This is because the spins in a QSL are highly entangled and fluctuate strongly down to... -
Single-Crystal Neutron Diffraction Study on [U(C5Me5)2(H)(mu¿H)]2
To our knowledge, the length of the U¿H single bond has never been accurately measured, at least not in a molecular compound by single-crystal neutron diffraction. We currently...
