Singlet-triplet dispersion reveals additional frustration in the triangular dimer compound BaMnO
M. B. Stone, M. D. Lumsden, S. Chang +3
We present single crystal inelastic neutron scattering measurements of the S=1 dimerized quasi-two-dimensional antiferromagnet BaMnO. The singlet-triplet dispersion rev…
Dispersive magnetic excitations in the S=1 antiferromagnet BaMnO
M. B. Stone, M. D. Lumsden, Y. Qiu +3
We present powder inelastic neutron scattering measurements of the S=1 dimerized antiferromagnet BaMnO. The K magnetic spectrum exhibits a spin-gap of $Δ\approx…
Field-driven phase transitions in a quasi-two-dimensional quantum antiferromagnet
M. B. Stone, C. Broholm, D. H. Reich +4
We report magnetic susceptibility, specific heat, and neutron scattering measurements as a function of applied magnetic field and temperature to characterize the quasi-two-…
Excitation spectrum of a model antiferromagnetic spin-trimer
M. B. Stone, F. Fernandez-Alonso, D. T. Adroja +4
We present an inelastic neutron scattering (INS) study of the excitation spectrum of a model S = 1/2 equilateral Heisenberg trimer, Cu_3(O_2C_16H_23)_6.1.2C_6H_12. Earlier measurem…
Temperature dependent bilayer ferromagnetism in Sr3Ru2O7
M. B. Stone, M. D. Lumsden, R. Jin +4
The Ruthenium based perovskites exhibit a wide variety of interesting collective phenomena related to magnetism originating from the Ru 4d electrons. Much remains unknown concernin…
Spin-dynamics of the low-dimensional magnet (CH3)2NH2CuCl3
M. B. Stone, W. Tian, G. E. Granroth +4
Dimethylammonium copper (II) chloride (also known as DMACuCl3 or MCCL) is a low dimensional S=1/2 quantum spin system proposed to be an alternating ferro-antiferromagnetic chain wi…
