Phase transition and charge density study of the m-carboxyphenyl ammonium phosphite

Against the above background, electron diffraction observations in particular, of the superlattices and diffuse scattering observed as a function of temperature in the

The dielectric strength and the critical frequency of the relaxation mechanisms connected with these two modes were obtained throughout the measurement temperature

temperature, where fluctuation efTects are expected to be small, our results are fully consistent with a low frequency conventional Drude response (with an additional

- The well known order-disorder X-type phase transition in NH.CJl has been investigated, using the Brillouin Scattering method.The hypersonic sound velocities and elastic

Errata - Structural study of the charge density wave phase transition of the blue bronze : K0.3MoO

2014 We present an ultrasonic investigation of the nematic-isotropic phase transition in p-azoxyanisole (PAA). Our measurements were performed at several frequencies

this last case that is depicted : it is quite clear that the Peierls transition is not a metal-insulator transition : the wave vector of the modulation is
