Magnetic excitations of Fe_{1+y}Se_xTe_{1-x} in magnetic and superconductive phases
P. Babkevich, M. Bendele, A. T. Boothroyd +5
We have used inelastic neutron scattering and muon-spin rotation to compare the low energy magnetic excitations in single crystals of superconducting Fe1.01Se0.50Te0.50 and non-sup…
Study of diffuse scattering under hydrostatic pressure in PbMg1/3Nb2/3O3
G -M Rotaru, B Padmanabhan, S N Gvasaliya +5
We report measurements of the evolution of the diffuse scattering in a single crystal PbMg1/3Nb2/3O3 as a function of hydrostatic pressure. Upon applying pressure the diffuse scatt…
Excitations from a chiral magnetized state of a frustrated quantum spin liquid
A. Zheludev, V. O. Garlea, A. Tsvelik +4
We study excitations in weakly interacting pairs of quantum spin ladders coupled through geometrically frustrated bonds. The ground state is a disordered spin liquid, that at high…
Coexistence of incommensurate magnetism and superconductivity in Fe_{1+y}Se_xTe_{1-x}
R. Khasanov, M. Bendele, A. Amato +10
We report an investigation into the superconducting and magnetic properties of Fe_{1+y}Se_{x}Te_{1-x} single crystals by magnetic susceptibility, muon spin rotation, and neutron di…
Magnetism in Geometrically Frustrated YMnO3 Under Hydrostatic Pressure Studied with Implanted Muons
T. Lancaster, S. J. Blundell, D. Andreica +10
The rare-earth ferroelectromagnet YMnO3 consists of weakly coupled triangular layers of S=2 spins. Below T_N ~ 70 K muon-spin relaxation data show two oscillatory relaxing signals…
Spin fluctuations in the stacked-triangular antiferromagnet YMnO3
B. Roessli, S. N. Gvasaliya, E. Pomjakushina +1
The spectrum of spin fluctuations in the stacked-triangular antiferromagnet YMnO3 was studied above the Neel temperature using both unpolarized and polarized inelastic neutron scat…
