Evolution of magnetic nanophases of Ni embedded in Al2O3 (001) matrix by xray magnetic circular dichroism
ARORA, SUNIL KUMAR; SHVETS, IGOR (Elsevier, 2010)We report on the element-specific magnetic characterization of Ni nanoparticles (NPs) embedded in Al2O3(001) matrix prepared by ion-implantation (Ni:5?1016-2?1017 ions cm-2) technique. The x-ray diffraction studies reveal ... -
Exposition of semiconducting and ferromagnetic properties of pulsed-laser-deposited thin films of LaFe1-xNixO3 (x=0.3, 0.4, and 0.5)
SHVETS, IGOR; ARORA, SUNIL KUMAR (American Institute of Physics, 2005)We have explored the possibility of ferromagnetic semiconducting property in the epitaxial thin films of LaFe1?xNixO3 x=0.3, 0.4, and 0.5 grown on 001 oriented LaAlO3 substrate. We observe that substitution of Ni in ... -
In-plane magnetic anisotropies in Fe3O4 films on vicinal MgO (100)
ARORA, SUNIL KUMAR; SHVETS, IGOR; MCGUIGAN, LOUISE ANN (American Physical Society, 2008)Ferromagnetic resonance was used to study the influence of vicinal (miscut) angle and film thickness on in-plane fourfold and uniaxial magnetic anisotropies in epitaxial Fe3O4 films grown on vicinal MgO(100) surfaces. The ... -
Magnetic moment investigations of epitaxial magnetite thin films
ARORA, SUNIL KUMAR; SHVETS, IGOR (AMERICAN INSTITUTE OF PHYSICS, 2008)In this report, we provide an x-ray magnetic circular dichroism (XMCD) study for 100?nm thick epitaxial magnetite (Fe3O4) films on MgO (001) and Al2O3 (0001) substrates. For XMCD, we recorded the surface sensitive total ... -
Structural and transport properties of Bi-substituted Co2MnO4
ARORA, SUNIL KUMAR; SHVETS, IGOR (American Physical Society, 2009)We report the structural and transport properties of the Bi-substituted Co2MnO4 multiferroic materials. Samples synthesized using the solid state reaction route with the composition BixCo2?xMnO4 (<0x<0.3) exhibit a single ...
