Neutron scattering measurements of critical exponents in CsMnBr3: A Z2≥1 antiferromagnet
Abstract
CsMnBr3 is an XY-like antiferromagnet on a stacked, triangular lattice with nearest-neighbor interactions. It orders antiferromagnetically at TN=8.3 K. We have used neutron scattering measurements of the frequency-integrated critical scattering in the paramagnetic state and magnetic Bragg peak intensity in the ordered state to determine the critical exponents γ, ν, and β. Based on these measurements we conclude that γ=1.01±0.08, ν=0.54±0.03, …
