We investigate the frequency dispersion of complex permeability in GHz range superparamagnetic nickel–zinc ferrite thin films with different Ni/Zn ratios using a microstrip probe. The films, comprising crystallites as small 3 nm and deposited by microwave-irradiation-assisted solvothermal method, exhibit coexistence two resonance characteristics—a ferromagnetic peak ([Formula: see text]) at ∼2 ...

Heterobimetallic NiZn complexes featuring metal centers in distinct coordination environments have been synthesized using diimine–dioxime ligands as binucleating scaffolds. A tetramethylfuran-containing ligand derivative enables a stable one-electron-reduced S 1⁄4 1/2 species to be accessed using Cp2Co as a chemical reductant. The resulting pseudo-square planar complex exhibits spectroscopic an...
