Effect of Ag addition on phase transitions of the Cu-22.26 at.%Al-9.93 at.%Mn alloy
(2013-02-20)
The phase transitions that occur in the Cu-22.26 at.%Al-9.93 at.%Mn and Cu-22.49 at.%Al-10.01 at.%Mn-1.53 at.%Ag alloys after slow cooling were studied using differential scanning calorimetry at different heating rates, ...
Optical phase transitions in photonic networks: a spin-system formulation
(American Physical Society, 2020-07)
We investigate the collective dynamics of nonlinearly interacting modes in multimode photonic settings. To this end, we have established a connection with the theory of spin networks. The emerging "photonic spins"are ...
Dielectric properties of Sr0.75Ba0.25Nb 2O6 thin films: Bias field, frequency and temperature dependence
(Taylor & Francis Ltd, 2002-01-01)
Ferroelectric strontium barium niobate solid solutions had received great attention due to their excellent pyroelectric, electrooptic and photorefractive properties. Furthermore, they usually also present very interesting ...
Completeness of beta-phase decomposition reaction in Cu-Al-Ag alloys
(Springer, 2012-08-01)
The completeness of beta-phase decomposition reaction in the Cu-11wt%Al-xwt%Ag alloys (x = 0, 1, 2, and 3) was studied using differential scanning calorimetry (DSC), X-ray diffractometry (XRD), and optical microscopy (OM). ...

Mechanism of phase formation in Pb(ZrxTi1-x)O3 synthesized by a partial oxalate method
(1996-06-01)
The phase formation mechanism, as well as the morphotropic phase boundary, of lead zirconate titanate (PZT) processed by a partial oxalate method was investigated by simultaneous thermal analysis (TG-DTA) and by qualitative ...

Hydrodynamics of phase transition fronts and the speed of sound in the plasma
(Elsevier Science, 2014-12)
The growth of bubbles in cosmological first-order phase transitions involves nontrivial hydrodynamics. For that reason, the study of the propagation of phase transition fronts often requires several approximations. A ...
Low-temperature phase transition in Dy
(Physical Review B, 1982)
We give a theoretical explanation for the low-temperature phase transition in Dy first
experimentally observed by Rhyne et al. Our results are in excellent agreement with experimental
observations. We also demonstrate that ...
Friction forces on phase transition fronts
(Iop Publishing, 2013-07)
In cosmological first-order phase transitions, the microscopic interaction of the phase transition fronts with non-equilibrium plasma particles manifests itself macroscopically as friction forces. In general, it is a ...
