The electrodeposition of soft, high magnetic moment alloys has become the critical fabrication step in manufacturing of magnetic recording heads. The need for ultimately high magnetic moment alloys (2.4 T CoFe) and the electrodeposition process capable of delivering magnetic structures with dimension in the range of several tens of nanometers are the new tasks that have to be addressed if the f...

Postgrowth thermal annealing of a CoFe/MgOs100d tunnel spin injector grown on a GaAs/AlGaAs quantum well structure results in a significantly increased spin injection efficiency as inferred from the polarization of heavy-hole electroluminescence from a quantum well optical detector. The as-deposited sample displayed an initial polarization at 100 K of 43%, which was increased to 52% after a 1 h...

In most ferromagnets the magnetization rotates from one domain to the next with no preferred handedness. However, broken inversion symmetry can lift the chiral degeneracy, leading to topologically rich spin textures such as spin spirals and skyrmions through the Dzyaloshinskii-Moriya interaction (DMI). Here we show that in ultrathin metallic ferromagnets sandwiched between a heavy metal and an ...

The deployment of hydrogen as an energy carrier is found to be a vital alternative fuel for the future. It expected that water electrolysis, powered by renewable sources, able scale‐up production. However, reaction kinetic oxygen evolution (OER) sluggish process, which predominantly limits efficiency electrolysis. This review recapitulates recent progress and efforts made in design development ...

CoFe\(_{2}\)O\(_{4}\)/Fe\(_{3}\)O\(_{4}\) nanocomposite particles were synthesized by using co-precipitation combined with hydrothermal methods. The phase composition, surface morphology and magnetic properties of the nanocomposites investigated X- ray diffraction, scanning electron microscopy vibrating sample magnetometer. Findings show that samples comprise two phases, Fe\(_{3}\)O\(_{4}\) are...

This article reports on a post-test only cluster randomized controlled trial that assessed the impact of exposure to Child-Optimized Financial Education (COFE) curriculum, delivered within Savings and Lending Communities (SILC) in Uganda, caregivers’ spending school healthcare expenses for children, financial self-efficacy. Participation SILCs with COFE was significantly associated caregivers p...

Summary. Electrochemical water decomposition as a crucial approach for the gradual growth of renewable energy has attracted extensive attention. Metal-organic frameworks (MOFs) which benefit from ultra-high specific surface area, controllable nanostructures, and excellent porosity have been widely used high activity catalyst by electrochemical means. Herein, composition morphology metal–organic...
