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

Mario Poirier, Alexandre Langlois, Claude Bourbonnais +3

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 l…
