Magneto- and Baro- Caloric Responses in Magnetovolumic Systems

, 2015
By means of a mean-field model extended to include magnetovolumic effects we study the effect of external fields on the thermal response characterized either by the isothermal entropy change and/or the adiabatic temperature change. The model includes two

Ultrafast broadband tuning of resonant optical nanostructures using phase change materials

, 2015
The functionalities of a wide range of optical and opto-electronic devices are based on resonance effects and active tuning of the amplitude and wavelength response is often essential.

Subthreshold electrical transport in amorphous phase-change materials

New Journal of Physics, 2015
Chalcogenide-based phase-change materials play a prominent role in information technology. In spite of decades of research, the details of electrical transport in these materials are still debated.

Resonant cavities with phase-changing materials

Optics Letters, 2017
Phase changing materials are commonly used for optical switching, limiting, and sensing. In many important cases, the change in the transmission characteristics of the optical material is caused by light-induced heating. We demonstrate that the incorporation of such optical materials in judiciously designed photonic structures can dramatically alter ...

Sensitivity of Numerical Predictions to the Permeability Coefficient in Simulations of Melting and Solidification Using the Enthalpy-Porosity Method

, 2019
The high degree of uncertainty and conflicting literature data on the value of the permeability coefficient (also known as the mushy zone constant), which aims to dampen fluid velocities in the mushy zone and suppress them in solid regions, is a critical

Local atomic arrangement and martensitic transformation in Ni$_{50}$Mn$_{35}$In$_{15}$: An EXAFS Study

, 2007
Heusler alloys that undergo martensitic transformation in ferromagnetic state are of increasing scientific and technological interest. These alloys show large magnetic field induced strains upon martensitic phase change thus making it a potential ...
