Magneto-elastic coupling in the spin-Peierls ground state of hydrogenated and deuterated (TMTTF)$_2$PF$_6$ salts

Autor: Poirier, Mario, Langlois, Alexandre, Bourbonnais, Claude, Foury-Leylekian, Pascale, Moradpour, Alec, Pouget, Jean-Paul

We report an ultrasonic study of the magneto-elastic coupling of the hydrogenated and deuterated (TMTTF)$_2$PF$_6$ organic salts. For both salts the temperature dependence of the longitudinal velocity along the c* axis displays a monotonic stiffening

Exploring the Charge-Ordering Transition in (TMTTF)$_2$X via Thermal Expansion Measurements

Autor: de Souza, Mariano, Hofmann, Daniel, Foury-Leylekian, Pascale, Moradpour, Alec, Pouget, Jean-Paul, Lang, Michael

We report results of high-resolution measurements of the \emph{c$^*$}-axis expansivity ($\alpha_{c^{*}}$) at the charge-ordering (CO) transition for the quasi-1D (TMTTF)$_{2}$X compounds with X = SbF$_6$ and Br and make a comparison with previous res

Report

Microwave dielectric study of spin-Peierls and charge ordering transitions in (TMTTF)$_2$PF$_6$ salts

Autor: Langlois, Alexandre, Poirier, Mario, Bourbonnais, Claude, Foury-Leylekian, Pascale, Moradpour, Alec, Pouget, Jean-Paul

We report a study of the 16.5 GHz dielectric function of hydrogenated and deuterated organic salts (TMTTF)$_2$PF$_6$. The temperature behavior of the dielectric function is consistent with short-range polar order whose relaxation time decreases rapid
