Structure and magnetic properties of Fe nanoparticles embedded in a Cr matrix

Structure and Magnetic Properties of Oxide Nanoparticles of Fe-Co-Ni Synthesized by Co-Precipitation Method

Oxide nanoparticles of Fe-Co-Ni were prepared in six different compositions by co-precipitation method. The as-synthesized nanoparticles were characterized by X-Ray Diffraction (XRD), Field Emission Scanning Electron microscope (FESEM), Fourier Transform Infrared (FT-IR) and Vibrating Sample Magnetometer  (VSM). It was found that the nanoparticles had mean crystalline size of 30-55 nm and spher...

Magnetic Nanoparticles Embedded in a Silicon Matrix

This paper represents a short overview of nanocomposites consisting of magnetic nanoparticles incorporated into the pores of a porous silicon matrix by two different methods. On the one hand, nickel is electrochemically deposited whereas the nanoparticles are precipitated on the pore walls. The size of these particles is between 2 and 6 nm. These particles cover the pore walls and form a tube-l...

Magnetocaloric Properties of Fe-Ni-Cr Nanoparticles for Active Cooling

Low cost, earth abundant, rare earth free magnetocaloric nanoparticles have attracted an enormous amount of attention for green, energy efficient, active near room temperature thermal management. Hence, we investigated the magnetocaloric properties of transition metal based (Fe70Ni30)100-xCrx (x = 1, 3, 5, 6 and 7) nanoparticles. The influence of Cr additions on the Curie temperature (TC) was s...
