A thin topological insulator (Bi2Te3) inserted between two single magnetic septuple layers of MnBi2Te4 is shown to convert the intrinsic antiferromagnetic interlayer coupling into robust ferromagnetism. As the Bi2Te3 spacer thickness increases from 1 to 4 quintuple layers, the weakening coercivity, Curie temperature, and interlayer coupling reveal ...

An innovative molecular spatial‐positioning shimming strategy is developed to optimize the electrical properties of poly(vinylidene fluoride) (PVDF). By intercalating polyethylene wax (PE wax) short‐chain molecules into PVDF's free volume, the film achieves a significantly enhanced energy density of 32.67 J cm−3.

Electrospinning a composite of PVDF, HfO2, and nano‐Cu transforms the discrete precursors into a continuous nanofiber mesh, forming a multi‐interface heterostructure with embedded nanoparticles. The presence of HfO2 and nano‐Cu at the fiber interfaces induces a highly aligned β‐phase, which enhances piezoelectric crystallinity and improves the material'

The HfxZr1‐xO2‐based ferroelectric/antiferroelectric bilayer capacitor exhibits morphotropic‐phase‐boundary behavior with a high dielectric constant (∼52) at 2 V. Phase engineering stabilizes o/t‐phase coexistence and suppresses m‐phase formation, enabling capacitance enhancement and self‐optimization under cycling for scalable low‐voltage, high‐κ ...
