Microscale single-layer ferromagnetic rings typically exhibit a magnetic vortex state at remanence, characterized by a flux-closed magnetic state with zero stray fields. Magnetic reversal in such systems yields a vanishing remanent magnetization. In contrast, the authors show that in individual layers in thin rings, which alternate magnetic and nonmagnetic materials NiFe/Cu/Co , layer-resolved ...
In this communication we present a new sol–gel route to obtain high quality BaFe12O19 thin films. X-ray analysis confirmed the crystal structure with a crystal size of 32 nm. Atomic force microscopy images determined the film thickness to be around 250 nm and a roughness factor of less than 40 nm where the grain size averaged around 150 nm. SQUID magnetometer data shows a magnetic behavior simi...
Isotropic sa mples of Barium Ferrite are prepared by coprecipit a tion method. To study the effect of sintering temperature on magnetic propeTl ies of Barium ferrite we have sintered the samples in diUerent temperature from 900 up to J 100°C. Mean partieal size and porosity of the samples are dete rmind by scanning electron miecroseop (SEM), magnetic phase and magnetic parameters are meas...
