Magnetic excitations in the geometric frustrated multiferroic CuCrO
M. Frontzek, J. T. Haraldsen, A. Podlesnyak +9
In this paper detailed neutron scattering measurements of the magnetic excitation spectrum of CuCrO in the ordered state below K are presented. The spectra a…
Co-existing Singlet and Ordered S=1/2 Moments in the Ground State of the Triclinic Quantum Magnet CuMoO4
S. Haravifard, K. Fritsch, T. Asano +8
CuMoO4 is a triclinic quantum magnet based on S = 1/2 moments at the Cu2+ site. It has recently attracted interest due to the remarkable changes in its chromic and volumetric prope…
Long-Range Magnetic Interactions in the Multiferroic Antiferromagnet
Feng Ye, Randy S. Fishman, Jaime A. Fernandez-Baca +6
The spin-wave excitations of the multiferroic have been measured in its low-temperature collinear commensurate phase using high-resolution inelastic neutron scattering…
Giant Anharmonic Phonon Scattering in PbTe
O. Delaire, J. Ma, K. Marty +8
Understanding the microscopic processes affecting the bulk thermal conductivity is crucial to develop more efficient thermoelectric materials. PbTe is currently one of the leading…
Kinetically Inhibited Order in a Diamond-Lattice Antiferromagnet
G. J. MacDougall, D. Gout, J. L. Zarestky +5
Frustrated magnetic systems exhibit highly degenerate ground states and strong fluctuations, often leading to new physics. An intriguing example of current interest is the antiferr…
