Phase dependence of the Thermal Memory Effect in Polycrystalline Ribbon and Bulk Ni55Fe19Ga26 Heusler Alloys
A. Vidal-Crespo, A. F. Manchón-Gordón, J. M. Martín-Olalla +5
The thermal memory effect, TME, has been studied in Ni55Fe19Ga26 shape memory alloys, fabricated as ribbons via melt-spinning and as pellets via arc-melting, to evaluate its depend…
Thermo-magnetic characterization of phase transitions in a Ni-Mn-In metamagnetic shape memory alloy
F. J. Romero, J. M. Martín-Olalla, J. S. Blázquez +4
The partially overlapped ferroelastic/martensitic and para-ferromagnetic phase transitions of a NiMnIn metamagnetic shape memory alloy have been studie…
Experimental method to determine specific heat and transition enthalpy at a first order phase transition: fundamentals and application to a NiMnIn Heusler alloy
F. J. Romero, M. C. Gallardo, J. -M. Martín-Olalla +1
A new method that characterizes thermal properties during a first-order phase transition is described. The technique consists in exciting the sample by a series of constant frequen…
Memory effect in triglycine sulfate induced by a transverse electric field: specific heat measurement
M C Gallardo, J M Martin-Olalla, F J Romero +2
The influence of a transverse electric field in the specific heat of triglycine sulphate (TGS) has been studied. The specific heat of TGS has been measured heating the sample from…
Influence of the electric field on the latent heat of the ferroelectric phase transition in KDP
Jose-Maria Delgado-Sanchez, Jose-Maria Martin-Olalla, Maria-Carmen Gallardo +3
The specific heat, heat flux (DTA trace) and dielectric constant of KDP ferroelectric crystal have been measured simultaneously for various electric fields with a conduction calori…
The order parameter-entropy relation in some universal classes: experimental evidence
J. M. Martin-Olalla, F. J. Romero, S. Ramos +3
The asymptotic behaviour near phase transitions can be suitably characterized by the scaling of with , where is the excess entropy and is the order par…
