Multiferroic tunnel junctions (MFTJs) have attracted considerable attention due to their multifunctional properties, which are valuable for nonvolatile memory devices. The recent advancements in van der Waals (vdW) multiferroic materials, combining ferromagnetic and ferroelectric provide an excellent platform exploring MFTJs at the atomic scale. In this study, we employ a combination of nonequilibrium Green's function density functional theory theoretically investigate spin-dependent...
Abstract Poly(ethylene octene) grafted with glycidyl methacrylate (POE‐ g ‐GMA) was prepared and used to toughen poly (lactic acid) (PLA) via reactive blending. It found that the notched Izod impact strength of PLA/POE‐ ‐GMA blends improved dramatically when content elastomer higher than 10 wt%.
