The magnetic excitation spectrum in Fe1.07Te
We propose to investigate the high energy magnetic spectrum in Fe1.07Te. We have previously investigated the fluctuations in Fe1.14Te in the incommensurate phase and have found... -
Magnetic excitations and quasi-1D to 3D crossover in the metal-organic framew...
The metal-organic framework (MOF) guanadinium copper formate is of interest in the quest towards rational design of multiferroic MOFs. It exhibits cooperative Jahn-Teller... -
Hourglass dispersion in overdoped manganites
Overdoped manganites were recently shown to exhibit stripe-like ordering of charges orbitals and magnetic moments. The magnetic excitations in these materials show close... -
Neutron Spin resonance in the Fe-based silicide superconductor LaFeSiH
The iron-based superconductors (Fe-SC) are one of the most active and challenging topics in condensed matter physics. Very recently some of us (F. Bernardini et al.) have... -
Spin-orbit coupling and spin dynamics in hexagonal iridate
Hexagonal iridate Na2IrO3 has recently been proposed as a candidate material to exhibit strong spin-orbit coupling effects which may stabilize a Mott insulating state with... -

The unique "hourglass"-type dispersion observed within several classes of hole-doped cuprates has garnered considerable theoretical and experimental interest. Here we propose to... -
Quantum spin excitations of Cr-jarosite
Within the field of condensed matter physics, the study of frustrated antiferromagnets is at the forefront of current research. In frustrated antiferromagnets, the geometry of... -
Spin excitations in La2O2Fe2OSe2 ¿ A Mott insulator candidate
We propose to map out the spin excitations in La2O2FeOSe2 using the MARI chopper spectrometer on a powder sample. Although the structure of La2O2FeOSe2 has some similarities to... -
Magnetic excitations in CrB2
CrB2, like MnB2, are transition metal diborides that have magnetically ordered ground states. Preliminary neutron (TAS) work and in house lab indicated that the dispersion has... -

Phonon dynamics in liquid gallium
We propose to measure the inelastic scattering S(Q,E) maps from gallium in its liquid phases across a wide range of temperatures. This proposal is based on a new prediction for... -
Solvent Segregation in Phase-Separated Li-NH3-MeNH2
We request 2 days on MAPS (or 3 days on MARI) to determine the extent of solvent segregation in a liquid-liquid phase-separated metal-amine: The Li-NH3-MeNH2 system. Recently we... -
Spin waves in as-grown PLCCO-- How doping without annealing affects the spin ...
We propose to study the spin wave excitations of nonsuperconducting single crystal Pr0.88LaCe0.12CuO4 (PLCCO). Previous experiments on superconducting PLCCO have shown that spin... -
