Superconductivity and magnetism are typically antithetical forms of order. After all, in conventional superconductors, magnetic impurities are destructive to superconductivity as they break Cooper pairs [1]. But the discovery in 1979 of so-called heavy fermion superconductivity, found near an antiferromagnetic phase, led to a shift in thinking on this subject [2]. Since then, some of the most i...

We construct the general free energy governing long-wavelength magnetism in two dimensional oxide heterostructures, which applies irrespective of the microscopic mechanism for magnetism. This leads, in the relevant regime of weak but non-negligible spin-orbit coupling, to a rich phase diagram containing in-plane ferromagnetic, spiral, cone, and Skyrmion lattice phases, as well as a nematic stat...

Magnetic bifunctional nanocatalyst supported on activated carbon (AC), CaO-Fe2O3/AC was synthesized via wet impregnation method and utilized for catalytic transesterification of waste cooking oil (WCO). A series characterization techniques were performed to determine acid-base properties, magnetism, thermal stability, crystallinity, chemical composition, surface morphology the catalyst. The BET...

TiO2 /Fe3O4 nanocomposites with various TiO2:Fe3O4 ratios were synthesized by an ultrasonic-assisted deposition-precipitation method and their UV-light decolorization of Congo dye and magnetic separation were investigated. The nanocomposite samples were characterized by scanning electron microscopy (SEM), powder X-ray diffraction (XRD), surface area analayzer (BET) and Fourier transform infrare...
