- W2904456491 abstract "In this thesis, the intrinsic magnetic characteristic of 10 nm FeCr oxide nanoparticles is studied. The nanoparticles is produced using the method of Spark discharge generation. Scanning electron microscope (SEM) is used to characterize the size distribution and coverage of deposited particle. Magnetic characterization is carried out using a magnetometer equipped with superconducting quantum interference device (SQUID). Temperature and external magnetic eld dependent measurements are done to study the magnetic properties. The image of surface reveals the majority of nanoparticle has the size of 9 to 12 nm. At this size the particle can be assumed single-domain state. The particle coverage is considered low with one particle per 10404 nm^2, thereby minimizing interparticle magnetic dipole-dipole interactions. Magnetic characteristics reveal the magnetic moment dynamic as the variation of thermal energy. The magnetic characterization reveals that the nanoparticles are superparamagnetic with a blocking temperature of 51 K. At a temperature of 2 K, the nanoparticles are in a blocked state and exhibit magnetic hysteresis similar to a ferromagnetic system. The future of magnetic nanoparticle lies on the alloyedparticle that consists of two or more elements. This research act as a preliminarystudy of alloy using Iron chrome oxide as test system before advancing to the more complex system. (Less)" @default.
