Incommensurate spin correlations in highly oxidized cobaltates LaSrCoO
Z. W. Li, Y. Drees, C. Y. Kuo +13
We observe quasi-static incommensurate magnetic peaks in neutron scattering experiments on layered cobalt oxides La2-xSrxCoO4 with high Co oxidation states that have been reported…
Electronic and magnetic nano phase separation in cobaltates LaSrCoO
Z. W. Li, Y. Drees, A. Ricci +11
The single-layer perovskite cobaltates have attracted enormous attention due to the recent observation of hour-glass shaped magnetic excitation spectra which resemble the ones of t…
Hour-glass magnetic excitations induced by nanoscopic phase separation in cobalt oxides LaSrCoO
Y. Drees, Z. W. Li, A. Ricci +10
The magnetic excitations in the cuprate superconductors might be essential for an understanding of high-temperature superconductivity. In these cuprate superconductors the magnetic…
k=0 magnetic structure and absence of ferroelectricity in SmFeO3
C. -Y. Kuo, Y. Drees, M. T. Fernández-Díaz +17
SmFeO3 has attracted considerable attention very recently due to the reported multiferroic properties above room-temperature. We have performed powder and single crystal neutron di…
Hour-glass magnetic spectrum in a stripe-less insulating transition metal oxide
Y. Drees, D. Lamago, A. Piovano +1
An hour-glass shaped magnetic excitation spectrum appears to be an universal characteristic of the high-temperature superconducting cuprates. Fluctuating charge stripes or alternat…
