Magneto-Optical Study of Cobalt Ferrite Nanoparticles
A magneto-optical study of CoxFe1-xFe2O4 nanoparticles is presented, with cobalt molar ratio 0.x.1. The ferrite nanoparticles were produced using a generic wet-chemical synthesis procedure. Stoichiometric amounts of Fe2+, Fe3+ and Co2+ salts are dissolved in a non-aqueous polar medium (diethylene …

Magneto-optical spectroscopic studies of multi-heme enzymes
Cytochrome cd1 (cd1) is a soluble, diheme enzyme located in the periplasm of denitrifying bacteria that catalyses the one-electron reduction of nitrite ion to nitric oxide. Paracoccus pantotrophus cd1 undergoes an unusual coordinated ligand switch upon reduction to the diferrous state, whereby a …

Magneto-optical studies of RirA and cytochrome cd1
Rhizobia are members of the Gram-negative α-proteobacteria. Rhizobium leguminosarum controls genes involved in iron uptake through repression under conditions of iron sufficiency. This part of iron regulation is co-ordinated by the dimeric rhizobial iron regulator, RirA. The sequence of RirA …

Magneto-optical oxide thin films and integrated nonreciprocal photonic devices
Nonreciprocal photonic devices including optical isolators and optical circulators are indispensible components in present day optical communication systems. Although highly desired by the fast development of silicon photonics, monolithically integrating such devices on a semiconductor platform has …

Sol-gel processing of RxY3-xAlyFe5-yO12 magneto-optical films
… research was the fabrication of thin films with magneto-optic (MO) properties. Accomplishment of this task was achieved via sol-gel processing of rare-earth and aluminum substituted yttrium-iron garnet (RxY3-xAlyFe5-yO12, R,Al:YIG), where R= Bi, Gd, Er, Ho. Detailed are the processing conditions, …
