Phase-Change Control of Interlayer Exchange Coupling [PDF]

, 2019
Changing the interlayer exchange coupling between magnetic layers in-situ is a key issue of spintronics, as it allows for the optimization of properties that are desirable for applications, including magnetic sensing and memory. In this paper, we utilize

Heat Transfer Performance Potential with a High-Temperature Phase Change Dispersion

Energies, 2021
Phase change dispersions are useful for isothermal cooling applications. As a result of the phase changes that occur in PCDs, they are expected to have greater storage capacities than those of single-phase heat transfer fluids.

Method for Estimating the Temperature Distribution in a Phase Change Material with a Broad Phase-change-temperature Range

Energy Procedia, 2015
AbstractWe have conducted this study to find an equation that is capable of predicting the temperature distribution in a semi-infinite phase change material (PCM) that has broad phase-change-temperature range on the condition that the initial temperature distribution is uniform at a lower temperature than the phase-change-temperature, and the surface ...
