Block magnetic excitations in the orbitally selective Mott insulator BaFe2Se3
M. Mourigal, Shan Wu, M. B. Stone +4
Iron pnictides and selenides display a variety of unusual magnetic phases originating from the interplay between electronic, orbital, and lattice degrees of freedom. Using powder i…
Synthesis, floating zone crystal growth and characterization of the Quantum Spin Ice pyrochlore
S. M. Koohpayeh, J. -J. Wen, B. A. Trump +2
Pyrochlore samples in the form of both powders and bulk single crystals have been studied to elucidate the depend…
Disorder from order among anisotropic next-nearest-neighbor Ising spin chains in SrHoO
J. -J. Wen, W. Tian, V. O. Garlea +7
We describe why Ising spin chains with competing interactions in segregate into ordered and disordered ensembles at low temperatures (). Using elastic neutron sc…
Heat capacity anomaly at the quantum critical point of the Transverse Ising Magnet CoNb_2O_6
Tian Liang, S. M. Koohpayeh, J. W. Krizan +3
The transverse Ising magnet Hamiltonian describing the Ising chain in a transverse magnetic field is the archetypal example of a system that undergoes a transition at a quantum cri…
Evolution of Magnetism in the Series of Honeycomb Iridates
D. C. Wallace, C. M. Brown, T. M. McQueen
The structural and magnetic properties of a new series of iridium-based honeycomb lattices with the formula Na3-delta(Na1-xMgx)Ir2O6 (x = 0 to 1) are reported. As x and delta are i…
Raman study of magnetic excitations and magneto-elastic coupling in alpha-SrCr2O4
Michael Valentine, Seyed Koohpayeh, Martin Mourigal +8
Using Raman spectroscopy, we investigate the lattice phonons, magnetic excitations, and magneto-elastic coupling in the distorted triangular-lattice Heisenberg antiferromagnet alph…
