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)…

Angular Dependent Spectral-Weight Transfer and Evidence for Symmetry Broken In-Plane Charge Response in CaNaCuOCl

R. Schuster, S. Pyon, M. Knupfer +4

We report about the energy and momentum dependent charge response in CaNaCuOCl employing electron energy-loss spectroscopy. Along the diagonal of the Brillo…

Two-Staged Magnetoresistance Driven by Ising-like Spin Sublattice in SrCo6O11

S. Ishiwata, I. Terasaki, F. Ishii +5

A two-staged, uniaxial magnetoresistive effect has been discovered in SrCo6O11 having a layered hexagonal structure. Conduction electrons and localized Ising spins are in different…

Pressure/temperature/substitution-induced melting of A-site charge disproportionation in Bi_(1-x)La_(x)NiO_3 (0 =< x =< 0.5)

S. Ishiwata, M. Azuma, M. Hanawa +8

Metal-insulator transitions strongly coupled with lattice were found in Bi1-xLaxNiO3. Synchrotron X-ray powder diffraction revealed that pressure (P ~ 3 GPa, T = 300 K), temperatur…

Different routes to charge disproportionation in perovskites-type Fe oxides

J. Matsuno, T. Mizokawa, A. Fujimori +3

Iron perovskites CaFeO_3 and La_{0.33}Sr_{0.67}FeO_3 show charge disproportionation, resulting in charge-ordered states with Fe^{3+}:Fe^{5+} =1:1 and =2:1, respectively. We have ma…
