Orbital magnetic moment and coercivity of SiO-coated FePt nanoparticles studied by x-ray magnetic circular dichroism
Y. Takahashi, T. Kadono, V. R. Singh +11
We have investigated the spin and orbital magnetic moments of Fe in FePt nanoparticles in the 1-ordered phase coated with SiO by x-ray absorption spectroscopy (XAS)…
Role of doped Ru in coercivity-enhanced LaSr_3$ thin film studied by x-ray magnetic circular dichroism
T. Harano, G. Shibata, K. Ishigami +15
The coercivity of LaSrMnO thin films can be enhanced by Ru substitution for Mn. In order to elucidate its mechanism, we performed soft x-ray absorption and magnetic…
Enhanced ferromagnetic moment in Co-doped BiFeO3 thin films studied by soft X-ray circular dichroism
V. R. Singh, V. K. Verma, K. Ishigami +10
BiFeO (BFO) shows both ferroelectricity and magnetic ordering at room temperature but its ferromagnetic component, which is due to spin canting, is negligible. Substitution of…
