X-ray absorption spectroscopy and X-ray magnetic circular dichroism studies of transition-metal-co-doped ZnO nano-particles
T. Kataoka, Y. Yamazaki, V. R. Singh +15
We report on x-ray absorption spectroscopy (XAS) and x-ray magnetic circular dichroism (XMCD) studies of the paramagnetic (Mn,Co)-co-doped ZnO and ferromagnetic (Fe,Co)-co-doped Zn…
Electronic structure and magnetism of the diluted magnetic semiconductor Fe-doped ZnO nano-particles
T. Kataoka, M. Kobayashi, Y. Sakamoto +16
We have studied the electronic structure of ZnFeO nano-particles, which have been reported to show ferromagnetism at room temperature, by x-ray photoemission spectr…
Magnetic Circular Dichroism spectroscopy in epitaxial La0.7Sr0.3MnO3 thin films
T. K. Nath, J. R. Neal, G. A. Gehring
Magneto optic measurements are a very powerful tool for investigating the polarization of a conduction band as a function of temperature and are used here to study the polarization…
Enhanced grain surface effect on magnetic properties of nanometric La0.7Ca0.3MnO3 manganite : Evidence of surface spin freezing of manganite nanoparticles
P. Dey, T. K. Nath, P. K. Manna +1
We have investigated the effect of nanometric grain size on magnetic properties of single phase, nanocrystalline, granular La0.7Ca0.3MnO3 (LCMO) sample. We have considered core-she…
Ferromagnetism in Fe-doped ZnO Nanocrystals: Experimental and Theoretical investigations
Debjani Karmakar, S. K. Mandal, R. M. Kadam +6
Fe-doped ZnO nanocrystals are successfully synthesized and structurally characterized by using x-ray diffraction and transmission electron microscopy. Magnetization measurements on…
Effect of substrate-induced strain on transport and magnetic properties of epitaxial La_0.66Sr_0.33MnO_3 thin films
Puja Dey, T. K. Nath, A. Taraphder
We have studied electrical transport and magnetic properties of epitaxial La_0.66 Sr_0.33 Mn O_3 thin films grown on different substrates having different lattice strains induced b…
