Anisotropic antiferromagnetic order in spin-orbit coupled trigonal lattice Ca2Sr2IrO6
Jieming Sheng, Feng Ye, Christina Hoffmann +6
We used single-crystal x-ray and neutron diffraction to investigate the crystal and magnetic structures of trigonal lattice iridate Ca2Sr2IrO6. The crystal structure is determined…
Electronic and magnetic properties of epitaxial SrRhO3 films
John Nichols, Simuck F. Yuk, Changhee Sohn +4
Strong interplay of fundamental order parameters in complex oxides are known to give rise to exotic physical phenomena. The 4d transition metal oxide SrRhO3 has generated much inte…
Antiferromagnetism in the van der Waals layered spin-lozenge semiconductor CrTe3
Michael A. McGuire, V. Ovidiu Garlea, Santosh KC +4
The crystallographic, magnetic, and transport properties of the van der Waals bonded, layered compound CrTe3 have been investigated on single crystal and polycrystalline materials.…
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…
Reversal of the lattice structure in SrCoOx epitaxial thin films studied by real-time optical spectroscopy and first-principles calculations
Woo Seok Choi, Hyoungjeen Jeen, Jun Hee Lee +4
Using real-time spectroscopic ellipsometry, we directly observed a reversible lattice and electronic structure evolution in SrCoOx (x = 2.5 - 3) epitaxial thin films. Drastically d…
Fractionally delta-doped oxide superlattices for higher carrier mobilities
Woo Seok Choi, Suyoun Lee, Valentino R. Cooper +1
A 2D electron gas system in an oxide heterostructure serves as an important playground for novel phenomena. Here, we show that, by using fractional delta-doping to control the inte…
