Pulsed Neutron Spectroscopy of Low Dimensional Magnets: Past, Present, and Future
Stephen E. Nagler, D. Alan Tennant
The early 1990s saw the first useful application of pulsed neutron spectroscopy to the study of excitations in low dimensional magnetic systems, with Roger Cowley as a key particip…

Longitudinal Magnetic Dynamics and Dimensional Crossover in the Quasi-One-Dimensional, Spin-1/2, Heisenberg Antiferromagnet KCuF3
B. Lake, D. A. Tennant, S. E. Nagler
The spin dynamics of coupled spin-1/2, antiferromagnetic Heisenberg chains is predicted to exhibit a novel longitudinal mode at low energies and temperatures below the Neel tempera…
