Characterization of ferromagnetic composite materials for biomedical applications

The great technological development in materials engineering together with quantum mechanical effect called giant magnetoresistance (GMR) observed in thin film structures composed of alternating ferromagnetic and nonmagnetic metal layers have evolved to the point where their synergistic combination have culminated in a new field of multidisciplinary research and in new applications. Paper shows results of investigations of nanocomposites consisting of magnetic metallic (alloy) nanoparticles (MMNPs) embedded in a dielectric matrix (like SiO2 or Al2O3). The studied (Fe0.45Co0.45Zr0.10)x(Al2O3)100-x(17
