Spin correlations in Ca3Co2O6: A polarised-neutron diffraction and Monte Carlo study
Joseph A. M. Paddison, Stefano Agrestini, Martin R. Lees +5
We present polarised-neutron diffraction measurements of the Ising-like spin-chain compound Ca3Co2O6 above and below the magnetic ordering temperature TN. Below TN, a clear evoluti…
Soft x-rays absorption and high-resolution powder x-ray diffraction study of superconducting CaxLa(1-x)Ba(1.75-x)La(0.25+x)Cu3Oy system
S. Agrestini, S. Sanna, K. Zheng +5
We have studied the electronic structure of unoccupied states measured by O K-edge and Cu L-edge x-ray absorption spectroscopy (XAS), combined with crystal structure studied by hig…
Spectroscopic evidence for giant orbital moment and magnetic anisotropy induced by local distortions in alpha-CoV2O6
N. Hollmann, S. Agrestini, Z. Hu +9
We present a combined experimental and theoretical study on the local magnetism of the Co ions in the spin-chain compound CoV2O6, which crystallizes in two different allotropic pha…
