Experimental determination of the spin Hamiltonian of the cubic chiral magnet MnSi
P. Dalmas de Reotier, A. Yaouanc, G. Lapertot +3
A thorough description of the physics of a magnetic compound requires the validation of its microscopic spin Hamiltonian. Here, from the analysis of muon-spin rotation spectra reco…
Long-range dynamical magnetic order and spin tunneling in the cooperative paramagnetic states of the pyrochlore analogous spinel antiferromagnets CdYb2X4 (X = S, Se)
P. Dalmas de Reotier, C. Marin, A. Yaouanc +6
Magnetic systems with spins sitting on a lattice of corner sharing regular tetrahedra have been particularly prolific for the discovery of new magnetic states for the last two deca…
Magnetic order, spin waves and fluctuations in the triangular antiferromagnet La2Ca2MnO7
P. Dalmas de Réotier, C. Marin, A. Yaouanc +4
We report magnetic susceptibility, specific heat and muon spin relaxation (muSR) experiments on the triangular antiferromagnet La2Ca2MnO7 which develops a genuine two-dimensional,…
Direct evidence for a dynamical ground state in the highly frustrated TbSnO pyrochlore
F. Bert, P. Mendels, A. Olariu +5
MuSR experiments have been performed on powder sample of the "ordered spin ice" TbSnO pyrochlore compound. At base temperature (T=35mK) the muon relaxation is found to…
Spin dynamics and magnetic order in magnetically frustrated Tb2Sn2O7
P. Dalmas de Reotier, A. Yaouanc, L. Keller +8
We report a study of the geometrically frustrated magnetic material Tb2Sn2O7 by the positive muon spin relaxation technique. No signature of a static magnetically ordered state is…
