Investigation of a spin-resonance in unconventional superconductor YFe2Ge2
In the layered iron-based superconductor YFe2Ge2, a high Sommerfeld ratio of order 100 mJ/mol K^2 and a T^3/2 temperature dependence of the electrical resistivity at low... -
Quantum critical dynamics in the presence of disorder
Quantum phase transitions are abrupt qualitative changes of a system's groundstate occurring only at exactly zero temperature. Such critical points - although never reachable... -
Dirac Nodal Line Magnons in a Stacked Honeycomb Magnet
On the basis of exchange couplings obtained from early inelastic neutron measurements, we conjecture that the stacked honeycomb magnet FeTiO3 contains Dirac nodal lines in the... -
Spinon Confinement and Longitudinal Interchain modes in Yb2Pt2Pb
The f-electron metal Yb2Pt2Pb is best thought of as a one dimensional (1D) quantum spin chain system, despite the fact that the magnetic moments are large and anisotropic with... -
Copy of: Field driven quantum phase transition in a Kitaev honeycomb magnet
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... -
Probing the mechanism of thermoelectric enhancement in Kondo insulator YbB12 ...
We propose to study the evolution of the spectral features in the dynamical magnetic response in series Yb_{1-x}Tm_{x}B_{12} (x=0.15, 0.6, 0.8). Tm doping results in non-trivial... -
Short range magnetic correlations in Gd3Ga5O12
In recent years topologically complex materials have provoked questions about the basic models of magnetism. These materials have given rise to unusual phenomena, including... -
Detecting an entanglement transition in a quantum magnet
Justification: We'd like to apply for three days Director’s Discretionary time on WISH to continue the experiment on measures of quantum entanglement in a model 1D magnet. This... -
Inelastic neutron scattering investigation of the giant phonon anomalies due ...
The electron-phonon interaction is a major factor influencing the competition between collective instabilities in correlated-electron materials, but its role in driving... -
X-ray Radiation damage to DNA at the atomic level
The interaction of ionizing radiation such as X-rays with biological samples causes damage to the samples. Recent work from our group with various protein crystals, peptides and... -
Pressure effect on stable and metastable structural phases in geometrically f...
Geometrically frustrated antiferromagnet LuBaCo4O7 exhibits unusual competition between two low-temperature phases with orthorhombic and monoclinic symmetry. Depending on... -
Neutron inelastic scattering of the possible quantum spin ice state of Nd2Zr2...
Nd2Zr2O7 is a new candidate for quantum spin ice proposed theoretically. It has a well-isolated dipolar-octupolar doublet with Ising anisotropy as the crystal field ground state... -
Martensite detwinning mechanisms of aged Co-Ni-Ga shape memory alloys
Pseudoelastic CoNiGa high-temperature shape memory alloys (HT-SMAs) show a wide range of transformation temperatures and lower processing costs than conventional Ni-Ti-X HT-SMAs... -
Evolution of the magnetic order in Yb(Rh(1-x)Cox)2Si2
In this proposal we want to clarify the magnetic structure on Yb(Rh(1-x)Cox)2Si2 by means of single neutron diffraction on SXD. In previous experiments we identified the... -
Magnetic Excitations on the Frustrated Triangular Lattice of UAu2
Nature abhors disorder and degeneracy at low temperature. Designing materials that confront this requirement can therefore lead to new states in which the degeneracy is lifted.... -
Nature of the new field-induced magnetic phase in ZnCr2Se4
ZnCr2Se4 is a magnetically frustrated spinel compound with an incommensurate helical ground state. It has a pyrochloremagnetic sublattice which is formed by Cr3+ (S = 3/2)... -

Spin Ladders in Metallic Yb2Pt2Pb
Yb2Pt2Pb is a first-in-class system where spin ladders are coupled to quasiparticles, made massive by strong quantum mechanical fluctuations. The classical Yb moments are... -
Defects and monopole dynamics in spin ice
We have determined the defect structure of oxygen-depleted Y2Ti2O7 using diffuse neutron scattering, and we find that these oxygen vacancies are also the dominant defects in... -
Interaction between slow dynamics of nuclear and magnetic domains in relaxor ...
Neutron experiment is carried out on relaxor magnet LuFeCoO4 to study the coupling between the slow dynamics of the dielectric and magnetic properties. At 190 K, the nuclear and...
