Autor: Marceli Koralewski, J. Manchado, J. Del Cerro, F J Romero, María Carmen Gallardo

Publikováno v: Ferroelectrics. 363:100-109

The tricritical phase transition of ferroelectric triglycine selenate (TGSe) has been investigated under the influence of weak uniaxial stress and electric fields by means of a high sensitive calorimetric technique. The effect of deuteration on the l

Publikováno v: Physical Review B. 81

The first-order diffusionless structural transition in Cu67.64Zn16.71Al15.65 is characterized by jerky propagation of phase fronts related to the appearance of avalanches. In this paper, we describe a full analysis of this avalanche behavior using ca

Square-modulated differential thermal analysis: measuring method

Autor: F J Romero, María Carmen Gallardo, J. Del Cerro, J. Manchado

Publikováno v: Measurement Science and Technology. 23:035003

A conduction calorimetry technique has been used to characterize qualitatively and quantitatively first-order phase transitions. A series of long-period square thermal pulses superimposed on a temperature ramp (square-modulated differential thermal a
