چکیده

Using an alternating reactive ion &am sputtering technique, Co ion was doped in epitaxially growing Bi3Fe5Ol, garnet film. The intense enhancement of magnetization, coercivity, and optical absorption at 633nm was observed. The Faraday hysteresis loop for slightly Cwdoped film showed anomalous behavior. Those phenomena can be understood considering the composite film structure in which fine particles of C O ~ . ~ F ~ # , spinel are embedded in epitaxially grown Bi,Fe@,,.

Magnetic and Magneto-optic Study of a Layered Co/Pt - Dysprosium-Iron-Garnet System

We have studied the effects of placing Co/Pt multilayers on dysprosium-iron-garnet doped with bismuth and aluminum. The garnet was deposited by RF-magnetron sputtering and crystallized by rapid thermal annealing. The Co/Pt multilayers were then deposited by DC-magnetron sputtering. The garnet thickness was held constant at lOOOA while the ColPt multilayer had the form of [3ACo/9APt], with n ran...

Room Temperature Ferromagnetism in Cobalt Doped ZnO Nanoparticles

In this work we report synthesis and magnetic characterization of cobalt doped ZnO nanoparticles (with different percent of doped cobalt oxide). Synthesis of the materials was carried out at room temperature by polyacrylamide-gel method, using zink sulfate and cobalt nitrate as source materials, acrylamide as monomer and N,N-methylene bisacrylamide as a lattice reagent. Characterization of the ...

Synthesis and Investigation of Optical and Magnetic Properties of Co-Doped effect on Zinc Oxide Nanoparticles

In this study, the effect of simultaneous doping of magnesium, calcium, and copper ions on the properties of zinc oxide doped with cobalt was investigated. The sol-gel method has been used for the synthesis of nanoparticles. The structural and optical properties of the synthesized nanoparticles were investigated using X-ray diffraction (XRD), infrared spectroscopy (FTIR), and DRS spectroscopy. ...
