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

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

Discontinuities in elastic constants are detected at the superconducting transition of layered organic conductors \kappa-(BEDT-TTF)_{2}X by longitudinal and transverse ultrasonic velocity measurements. Symmetry arguments show that discontinuities in

We report a study of the microwave conductivity of electron-doped Pr$_{1.85}$Ce$_{0.15}$CuO$_{4-\delta}$ superconducting thin films using a cavity perturbation technique. The relative frequency shifts obtained for the samples placed at a maximum elec

We report an ultrasonic investigation of the elastic moduli on a single crystal of hexagonal YMnO_3 as a function of temperature. Stiffening anomalies in the antiferromagnetic N\'eel state below T_N = 72.4 K are observed on all the four elastic modul

Ultrasonic velocity and attenuation measurements on the quasi-two-dimensional organic conductor $\kappa$-[BEDT-TTF]$_2$Cu[N(CN)$_2$]Br give the first determination of the coexistence zone of the antiferromagnetic and superconducting phases which exte

We have used thermal conduction and transverse sound attenuation to probe the anisotropy of the gap structure in two superconducting phases of UPt$_3$. For the low-temperature phase B, transverse sound has in the past provided strong evidence for a l

We have measured the transverse ultrasonic attenuation, $\alpha_{q\epsilon}$, in a well-characterized single crystal of $UPt_3$ for propagation direction, ${\bf q}$, in the basal plane and polarization, $\epsilon$, in and out of the plane. Unlike pre

Vivre à la rue n’est pas une sinécure pour qui que ce soit, mais cela devient très ardu à un âge avancé alors que l’état de santé de l’individu se fragilise et que son réseau social tend à s’étioler. Tenant compte du vieillissement

Marche, train Voyage, accident. On l’a vu en parlant de relations familiales, par l’ultime lettre au père, à l’âge où Félix était devenu père de Louis, Louis refusait devant son père d’endosser l’habit social de la paternité et mou
