Multiferroic behavior confined by symmetry in EuTiO3 films
P. J. Ryan, G. E. Sterbinsky, Y. Choi +11
We have elucidated the spin, lattice, charge and orbital coupling mechanism underlying the multiferroic character in tensile strained EuTiO3 films. Symmetry determined by oxygen oc…
Itinerant ferromagnetism in the As 4 conduction band of BaKMnAs identified by x-ray magnetic circular dichroism
B. G. Ueland, Abhishek Pandey, Y. Lee +9
X-ray magnetic circular dichroism (XMCD) measurements on single-crystal and powder samples of BaKMnAs show that the ferromagnetism below $T_{\textrm{C}}…
Giant spin-phonon-electronic coupling in a 5d oxide
S. Calder, J. H. Lee, M. B. Stone +8
Enhanced coupling of material properties offers new fundamental insights and routes to multifunctional devices. In this context 5d oxides provide new paradigms of cooperative inter…
Spin polarization of Ru in superconducting Ba(FeRu)As studied by x-ray resonant magnetic scattering
M. G. Kim, J. Soh, J. Lang +8
We have employed the x-ray resonant magnetic scattering (XRMS) technique at the Ru edge of the Ba(FeRu)As () superconductor. We show that prono…
Continuous and Discontinuous Quantum Phase Transitions in a Model Two-Dimensional Magnet
S. Haravifard, A. Banerjee, J. C. Lang +5
The Shastry-Sutherland model, which consists of a set of spin 1/2 dimers on a 2-dimensional square lattice, is simple and soluble, but captures a central theme of condensed matter…
Fermi-surface induced modulation in an optimally doped YBCO superconductor
Xuerong Liu, Zahirul Islam, Sunil K. Sinha +4
We have observed a Fermi-surface (FS) induced lattice modulation in a YBCO superconductor with a wavevector along CuO chains, {\it i.e.} =(0,,0). The value of $δ\sim0…
