Room Temperature Dy Spin‐Flop Switching in Strained DyFeO3 Thin Films

Advanced Materials Interfaces, EarlyView.
The two‐spin system DyFeO3, a canted bulk antiferromagnet with a spin reorientation between 40 and 50 K is epitaxially grown as thin film with compressive in‐plane strain. As a result, the spin reorientation increased by more than 20 K and a sign‐dependent linear M(T) dependence between 100 and 400 K is measured due to an induced alignment of Dy spins.

The Rise of Refractory Transition‐Metal Nitride Films for Advanced Electronics and Plasmonics

Advanced Materials Interfaces, EarlyView.
Transition‐metal nitrides (TMNs) are exceptional materials with high stability, biocompatibility, and semiconductor integration, which have been extensively employed in various fields. However, the epitaxial growth of TMN films remains a challenge. The absence of high‐quality TMNs limits the understanding of their condensed matter physics and hinders ...

Phase Engineering for Enhanced Piezoresponse in P(VDF‐TrFE) and Its Composites

Advanced Materials Interfaces, EarlyView.
As the temperature approaches the Curie point, the crystalline phase in P(VDF‐TrFE) decreases proportionally, while the amorphous phase increases. This shift leads to the formation of more interphase regions. Although spontaneous polarization from crystalline regions decreases, the interphase regions enable additional deformation, thereby enhancing the
