AI Article Synopsis

  • Multiferroic heterostructures are created using Pb(Zr0·52Ti0·48)O3 and Fe0.7Ga0.3 thin films on Si cantilevers, allowing for advanced integration.
  • These structures operate in a non-linear regime, enhancing the coupling between mechanical and magnetic/electric properties.
  • Bistable dynamic states are developed that can be switched back and forth using DC magnetic and electric fields, enabling tunability of the resonant frequency.

Article Abstract

Multiferroic heterostructures consisting of Pb(Zr0·52Ti0·48)O3 and Fe0.7Ga0.3 thin films are integrated on microfabricated Si cantilevers, and they are operated in a non-linear regime. Enhanced mechanical coupling at the multiferroic interface and tunability of the resonant frequency are used to devise bistable dynamic states that can be reversibly switched by both DC magnetic and electric fields.

Accurate DFT simulation of complex functional materials: Synergistic enhancements achieved by SCAN meta-GGA.

Complex functional materials are characterized by intricate and competing bond orders, making them an excellent platform for evaluating the newly developed strongly constrained and appropriately normed (SCAN) density functional. In this study, we explore the effectiveness of SCAN in simulating the electronic properties of displacive ferroelectrics (BaTiO3 and PbTiO3) and magnetoelectric multiferroics (BiFeO3 and YMnO3), which encompass a broad spectrum of bonding characteristics. Due to a significant reduction in self-interaction error, SCAN manifests its improvements over the Perdew-Burke-Ernzerhof (PBE) method in three aspects: SCAN predicts more accurate ionicity, produces more compact orbitals, and better captures d-orbital anisotropy.

Organic semiconductors, characterized by their exceptionally long spin relaxation times (≈ms) and unique spinterface effects, are considered game-changers in spintronics. However, achieving high-performance and wide-range tunable magnetoresistance (MR) in organic spintronic devices remains challenging, severely limiting the development of organic spintronics. This work combines straintronic multiferroic heterostructures with organic spin valve (OSV) to develop a three-terminal OSV device with a gate structure.

Photocurrent Spectroscopy of Dark Magnetic Excitons in 2D Multiferroic NiI.

Two-dimensional (2D) antiferromagnetic (AFM) semiconductors are promising components of opto-spintronic devices due to terahertz operation frequencies and minimal interactions with stray fields. However, the lack of net magnetization significantly limits the number of experimental techniques available to study the relationship between magnetic order and semiconducting properties. Here, they demonstrate conditions under which photocurrent spectroscopy can be employed to study many-body magnetic excitons in the 2D AFM semiconductor NiI.
