We present a HREM study performed on PbK 2 LiNb 5 O 15 at room temperature where the compound presents a ferroelectric and ferroelastic phase. The results display ferroelastic domains and the quality of images allows the use of CRISP software which p

This work presents X-ray diffraction results on the f - g first order phase transition in FePO 4 . An intermediate phase appears in a temperature range that corresponds to the excess of heat capacity previously attributed to a modulated phase. By mea

We present dielectric studies carried out on PbK2LiNb5O15 exhibiting its ferroelectric behaviour: the real part of dielectric constant follows a Curie law, with Tc = 639 K and a Curie constant 1.5x105 K. The structural change involves a first order p

In-plane and out-of-plane resistivity versus temperature measurements have been carried out on different kinds of as-grown Bi-2212 crystals: ρ ab ( T ) and ρ c ( T ); ρ c ( T ) has been specially used for determination of the 2D or 3D character of

In this work we report on the intercalation of single crystals of Bi 2 Sr 2 CaCu 2 O 8 with iodine to form the stage-1 intercalated complex IBi 2 Sr 2 CaCu 2 O 8 , and on the electrical resistivity of this final product, both as a function of tempera
