A Prototype Compact Accelerator Driven Neutron Source for Canada Supporting Medical and Scientific Applications
Dalini D. Maharaj, Mina Abbaslou, Sana Tabbassum +7
Canada recently lost its major supply of neutron beams with the closure of the National Research Universal reactor at Chalk River Laboratories in March 2018. This issue is further…
A Prototype Compact Accelerator-based Neutron Source (CANS) for Canada
Robert Laxdal, Dalini Maharaj, Mina Abbaslou +11
Canada's access to neutron beams for neutron scattering was significantly curtailed in 2018 with the closure of the National Research Universal (NRU) reactor in Chalk River, Ontari…
Multipolar magnetism in d-orbital systems: Crystal field levels, octupolar order, and orbital loop currents
Sreekar Voleti, Dalini D. Maharaj, Bruce D. Gaulin +2
Quantum magnets with spin , which arise in spin-orbit coupled Mott insulators, can potentially display multipolar orders. We carry out an exact diagonalization study of a simp…
Octupolar vs Néel Order in Cubic 5 double perovskites
Dalini D. Maharaj, Gabriele Sala, Matthew B. Stone +7
We report time-of-flight neutron spectroscopic and diffraction studies of the 5 cubic double pervoskite magnets, BaMOsO ( = Zn, Mg, Ca). These cubic materials are a…
Octupolar order in d-orbital Mott insulators
Arun Paramekanti, Dalini D. Maharaj, Bruce D. Gaulin
Motivated by experimental and theoretical interest in realizing multipolar orders in -orbital materials, we discuss the quantum magnetism of ions which can be realized…
Two-dimensional spin liquid behaviour in the triangular-honeycomb antiferromagnet TbInO
Lucy Clark, Gabriele Sala, Dalini D. Maharaj +9
Spin liquid ground states are predicted to arise within several distinct scenarios in condensed matter physics. The observation of these disordered magnetic states is particularly…
Spin gaps in the ordered states of LaLiXO (X = Ru, Os) and their relation to distortion of the cubic double perovskite structure in 4 and 5 magnets
D. D. Maharaj, G. Sala, C. A. Marjerrison +3
Time-of-flight inelastic neutron scattering measurements have been carried out on polycrystalline samples of the 4 and 5 double pervoskite antiferromagnets LaLiRuO$_6…
Crystal field excitations from ions at defective sites in highly stuffed
Gabriele Sala, Dalini D. Maharaj, Matthew B. Stone +2
The pyrochlore magnet has been proposed as a quantum spin ice candidate, a spin liquid state expected to display emergent quantum electrodynamics with gauge photo…
Magnetic dilution and domain selection in the XY pyrochlore antiferromagnet ErTiO
J. Gaudet, A. M. Hallas, D. D. Maharaj +7
Below K, the XY pyrochlore ErTiO orders into a non-collinear, antiferromagnetic structure referred to as the state. The magnetic order in ErT…
Gapped and gapless short range ordered magnetic states with wavevectors in the pyrochlore magnet TbTiO
E. Kermarrec, D. D. Maharaj, J. Gaudet +9
Recent low temperature heat capacity (C) measurements on polycrystalline samples of the pyrochlore antiferromagnet TbTiO have shown a strong sensitivity…
Neutron Spectroscopic Study of Crystalline Electric Field Excitations in Stochiometric and Lightly Stuffed Yb2Ti2O7
J. Gaudet, D. D. Maharaj, G. Sala +6
Time-of-flight neutron spectroscopy has been used to determine the crystalline electric field (CEF) Hamiltonian, eigenvalues and eigenvectors appropriate to the = 7/2 Yb…
The frustrated FCC antiferromagnet Ba2YOsO6: structural characterization, magnetic properties and neutron scattering studies
E. Kermarrec, C. A. Marjerrison, C. M. Thompson +8
We report the crystal structure, magnetization and neutron scattering measurements on the double perovskite BaYOsO. The space group is found both at 290~K…
