Structure and Magnetic Properties of Melilite-Type Compounds REBeGeO (RE = Pr, Nd, Gd-Yb) with Rare-Earth Ions on Shastry-Sutherland Lattice.

Rare-earth (RE)-based frustrated magnets, such as typical systems of combining strong spin-orbit coupling (SOC), geometric frustration, and anisotropic exchange interaction, can give rise to diverse exotic magnetic ground states such as quantum spin liquid. The discovery of new RE-based frustrated materials is crucial for exploring the exotic magnetic phases. Herein, we report the synthesis, structure, and magnetic properties of a family of melilite-type REBeGeO (RE = Pr, Nd, and Gd-Yb) compounds crystallized in a tetragonal 4̅2 structure, where magnetic RE ions lay out on the Shastry-Sutherland lattice (SSL) within the plane and are well separated by nonmagnetic [GeBeO] polyhedrons along the -axis.

A comparative study on magnetic order and field-induced magnetic transition in double perovskite iridates: REZnIrOand REMgIrO(RE = Pr, Nd, Sm, Eu, Gd).

We perform a comparative magnetic study on two series of rare-earth (RE) based double perovskite iridates REBIrO(RE = Pr, Nd, Sm-Gd; B = Zn, Mg), which show Mott insulating state with tunable charge energy gap from ∼330 meV to ∼560 meV by changing RE cations. For nonmagnetic RE = Eu cations, EuMgIrOshows antiferromagnetic (AFM) order and field-induced spin-flop transitions below Néel temperature () in comparison with the ferromagnetic (FM)-like behaviors of EuZnIrOat low temperatures. For magnetic-moment-containing RE ions, GdBIrOshow contrasting magnetic behaviors with FM-like transition (B = Zn) and AFM order (B = Mg), respectively.

A New Family of Disorder-Free Rare-Earth-Based Kagome Lattice Magnets: Structure and Magnetic Characterizations of REBWO (RE = Pr, Nd, Gd-Ho) Boratotungstates.

Exploration of rare-earth (RE)-based Kagomé lattice magnets with spin-orbital entangled = 1/2 moments will provide a new platform for investigating the exotic magnetic phases. Here, we report a new family of REBWO (RE = Pr,Nd,Gd-Ho) boratotungstates with magnetic RE ions arranged on Kagomé lattice and perform its structure and magnetic characterizations. These serial compounds crystallize in a hexagonal coordinated structure with space group 6 (no.

Polymer Matrix Nanocomposites with 1D Ceramic Nanofillers for Energy Storage Capacitor Applications.

Recent developments in various technologies, such as hybrid electric vehicles and pulsed power systems, have challenged researchers to discover affordable, compact, and super-functioning electric energy storage devices. Among the existing energy storage devices, polymer nanocomposite film capacitors are a preferred choice due to their high power density, fast charge and discharge speed, high operation voltage, and long service lifetime. In the past several years, they have been extensively researched worldwide, with 0D, 1D, and 2D nanofillers being incorporated into various polymer matrixes.

The effect of carrier doping on magnetism and electronic behavior in double perovskite LaZnIrO.

Tuning of spin-orbit coupling and electron correlation effects in iridates by introducing electron or hole carriers can produce interesting physical phenomena. In this work, we experimentally investigate the electron/hole doping effect on magnetism and electrical transport in the canted antiferromagnetic (AFM) double perovskite LaZnIrO, where hole/electron doping are realized in two serial LaZn Li IrO (0  ⩽  x  ⩽  0.35) and LaZnGa IrO (0  ⩽  y   ⩽  0.
