Comprehensive Control of Metamagnetic Transition of Antiferromagnetic Mott Insulator Sr2IrO4 by in-situ Anisotropic Strain
H. Zhang, L. Hao, J. Yang +10
Metamagnetism in antiferromagnets exhibits distinct critical behaviors and dynamics when invoking spin reversal and rotation. Here we show a 0.05% anisotropic strain suffices to in…
Strong anisotropy within a Heisenberg model in the J=1/2 insulating state of Sr2Ir0.8Ru0.2O4
S. Calder, J. W. Kim, A. E. Taylor +5
The dispersive magnetic excitations in Sr2IrO4 have previously been well described within an isospin-1/2 Heisenberg model on a square lattice that revealed parallels with La2CuO4.…
Evolution of competing magnetic order in the Jeff=1/2 insulating state of Sr2Ir1-xRuxO4
S. Calder, J. W. Kim, G. -X. Cao +11
We investigate the magnetic properties of the series Sr2Ir1-xRuxO4 with neutron, resonant x-ray and magnetization measurements. The results indicate an evolution and coexistence of…
Selective Interface Control of Order Parameters in Complex Oxides
D. Meyers, Jian Liu, J. W. Freeland +7
In complex materials observed electronic phases and transitions between them often involves coupling between many degrees of freedom whose entanglement convolutes understanding of…
Ferroelectric and Magnetic Domains in LuFe2O4 Observed by Scanning Probe Microscopy
I. K. Yang, J. Kim, S. H. Lee +3
LuFe2O4 is a multiferroic system which exhibits ferroelectricity, charge order, and ferrimagnetic order simultaneously below ~230 K. The ferroelectric domains of LuFe2O4 are imaged…
Jeff=1/2 Mott spin-orbit insulating state close to the cubic limit in Ca4IrO6
S. Calder, G. -X Cao, S. Okamoto +7
The Jeff=1/2 state is manifested in systems with large cubic crystal field splitting and spin-orbit coupling that are comparable to the on-site Coulomb interaction, U. 5d transitio…
