Unexpected phase locking of magnetic fluctuations in the multi-k magnet USb

Lim, J. A. ; Blackburn, E. LU ; Magnani, N. ; Hiess, Arno LU ; Regnault, L. -P. ; Caciuffo, R. and Lander, G. H. (2013) In Physical Review B (Condensed Matter and Materials Physics) 87(6).
Abstract
The spin waves in the multi-k antiferromagnet USb soften and become quasielastic well below the antiferromagnetic ordering temperature T-N. This occurs without a magnetic or structural transition. It has been suggested that this change is in fact due to dephasing of the different multi-k components: a switch from 3-k to 1-k behavior. In this work, we use inelastic neutron scattering with tridirectional polarization analysis to probe the quasielastic magnetic excitations and reveal that the 3-k structure does not dephase. More surprisingly, the paramagnetic correlations also maintain the same clear phase correlations well above T-N ( up to at least 1.4T(N)). DOI: 10.1103/PhysRevB.87.064421
