Dynamical ground state in the XY pyrochlore Yb2GaSbO7

Publikováno v: npj Quantum Materials, Vol 6, Iss 1, Pp 1-9 (2021)

Abstract The magnetic ground state of the pyrochlore Yb2GaSbO7 has not been established. The persistent spin fluctuations observed by muon spin-relaxation measurements at low temperatures have not been adequately explained for this material using exi

Hierarchical excitations from correlated spin tetrahedra on the breathing pyrochlore lattice

Autor: Qiang Zhang, David S. Parker, Ganesh Pokharel, Andrew D. Christianson, Andrew F. May, Georg Ehlers, J. A. M. Paddison, Matthew B. Stone, David Mandrus, Hasitha Suriya Arachchige, Shang Gao, Clarina Dela Cruz, Mao-Hua Du

The hierarchy of the coupling strengths in a physical system often engenders an effective model at low energies where the decoupled high-energy modes are integrated out. Here, using neutron scattering, we show that the spin excitations in the breathi

Cluster Frustration in the Breathing Pyrochlore Magnet LiGaCr4S8

Autor: Andrew D. Christianson, Hasitha Suriya Arachchige, Andrew Wildes, Randy Scott Fishman, Travis Williams, Ganesh Pokharel, David S. Parker, Georg Ehlers, J. A. M. Paddison, Tao Hong, Gabriele Sala, Andrew F. May, David Mandrus, Stuart Calder

Publikováno v: Physical Review Letters. 125

We present a comprehensive neutron scattering study of the breathing pyrochlore magnet LiGaCr_{4}S_{8}. We observe an unconventional magnetic excitation spectrum with a separation of high- and low-energy spin dynamics in the correlated paramagnetic r

Magnetic Excitations of the Classical Spin Liquid MgCr_{2}O_{4}

Autor: X, Bai, J A M, Paddison, E, Kapit, S M, Koohpayeh, J-J, Wen, S E, Dutton, A T, Savici, A I, Kolesnikov, G E, Granroth, C L, Broholm, J T, Chalker, M, Mourigal

Publikováno v: Physical review letters. 122(9)

We report a comprehensive inelastic neutron-scattering study of the frustrated pyrochlore antiferromagnet MgCr_{2}O_{4} in its cooperative paramagnetic regime. Theoretical modeling yields a microscopic Heisenberg model with exchange interactions up t

Statics and dynamics of the highly correlated spin ice Ho2Ge2O7

Autor: A M Hallas, J A M Paddison, H J Silverstein, A L Goodwin, J R Stewart, A R Wildes, J G Cheng, J S Zhou, J B Goodenough, E S Choi, G Ehlers, J S Gardner, C R Wiebe, H D Zhou

The pyrochlore Ho 2Ge 2O 7 is a new highly correlated spin ice material. Physical property measurements, including x-ray diffraction, dc susceptibility, and ac susceptibility, confirm that it shares the distinctive characteristics of other known spin
