“…probe of the lattice properties. We shall emphasize that we have considered the short range fourth order spin-crystal field interaction as previously done for RbCdF3 : Gd3 + below T~ [9]. Therefore, the condition of validity of the model developed by Blinc, i.e.…”

The shape of the E.P.R. line ΔMS : |5/2| → |7/2| for the Gd3+-n.n.n. V(Br-) centre, can be consistently interpreted by assuming a modulated rotation around the c crystal axis of the Th-Br bonds as an essential component of the displacement field in the incommensurate phase. The sensitivity of the local Gd3+ probe arises from the high value of the fourth order parameter b44 linked to the flat configuration of the n.n. Br- tetrahedron. We report preliminary results and we outline possible developments of the present investigation

“…3). Measurements, on other crystals with sensitive probes [11,12] indicate that the experimental device which has been used has a thermal equilibrium time less than 3 min. At stabilized temperature ( ± 0.1 K), a measurement can last less than 2 s and can be repeated every 5 s. In comparison with other techniques (N.M.R.…”

2014 Nous décrivons les résultats préliminaires d'une étude par R.P.E. de la phase incommensurable de Rb2ZnCl4 : Mn2+. Nous utilisons une raie de structure fine particulière pour contrôler la densité des domaines commensurables dans la phase incommensurable et pour discriminer le régime de modulation sinusoidale du régime de soliton. On observe, à Tc + 03B5, des temps d'équilibre très longs, lorsque le cristal est soumis à un saut de température.Abstract. 2014 We report preliminary results of an E.P.R. investigation on the incommensurate phase of Rb2ZnCl4 : Mn2+. We use a particular fine structure line to monitor the density of commensurate domains in the incommensurate phase and to discriminate the plane wave modulation regime from the soliton regime. Long equilibrium times are observed at Tc + 03B5, when the crystal is submitted to a thermal jump.
