Mn3TeO6 - A New Multiferroic Material with Two Magnetic Substructures
L. Zhao, Z. Hu, C. Y. Kuo +4
From magnetic susceptibility, dielectric permittivity, electric polarization and specific heat measurements, we discover spin-induced ferroelectricity and magnetoelectric coupling…
Large anomalous Hall effect driven by non-vanishing Berry curvature in non-collinear antiferromagnetic Mn3Ge
Ajaya K. Nayak, Julia Fischer, Yan Sun +9
It is well established that the anomalous Hall effect that a ferromagnet displays scales with its magnetization. Therefore, an antiferromagnet that has no net magnetization should…
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…
Control of multiferroic domains by external electric fields in TbMnO3
Jonas Stein, Max Baum, Simon Holbein +3
The control of multiferroic domains through external electric fields has been studied by dielectric measurements and by polarized neutron diffraction on single-crystalline TbMnO$_3…
Electronic and Spin States of SrRuO3 Thin Films: an X-ray Magnetic Circular Dichroism Study
S. Agrestini, Z. Hu, C. -Y. Kuo +14
We report a study of the local magnetism in thin films of SrRuO3 grown on (111) and (001) oriented SrTiO3 substrates using x-ray magnetic circular dichroism spectroscopy (XMCD) at…
