Unconventional anomalous Hall effect from antiferromagnetic domain walls of Nd2Ir2O7 thin films
Woo Jin Kim, John H. Gruenewald, Taekoo Oh +11
Ferroic domain walls (DWs) create different symmetries and ordered states compared with those in single-domain bulk materials. In particular, the DWs of an antiferromagnet (AFM) wi…
Electronic and optical properties of La-doped SrIrO epitaxial thin-films
M. Souri, J. Terzic, J. M. Johnson +7
We have investigated structural, transport, and optical properties of tensile strained (SrLa)IrO (x = 0, 0.025, 0.05) epitaxial thin-films. While High-T…
Optical Signatures of Spin-Orbit Exciton in Bandwidth Controlled SrIrO Epitaxial Films via High-Concentration Ca and Ba Doping
M. Souri, B. H. Kim, J. H. Gruenewald +8
We have investigated the electronic and optical properties of (SrCa)IrO (x= 0 - 0.375) and (SrBa)IrO (y= 0 - 0.375) epitaxial thin-films,…
Engineering One-Dimensional Quantum Stripes from Superlattices of Two-Dimensional Layered Materials
J. H. Gruenewald, J. Kim, H. S. Kim +10
One-dimensional (1D) quantum systems, which are predicted to exhibit novel states of matter in theory, have been elusive in experiment. Here we report a superlattice method of crea…
Selective growth of epitaxial Sr2IrO4 by controlling plume dimensions in pulsed laser deposition
S. S. A. Seo, J. Nichols, J. Hwang +6
We report that epitaxial Sr2IrO4 thin-films can be selectively grown using pulsed laser deposition (PLD). Due to the competition between the Ruddlesden-Popper phases of strontium i…
Enhanced metallic properties of SrRuO3 thin films via kinetically controlled pulsed laser epitaxy
J. Thompson, J. Nichols, S. Lee +10
Metal electrodes are a universal element of all electronic devices. Conducting SrRuO3 (SRO) epitaxial thin films have been extensively used as electrodes in complex-oxide heterostr…
Investigations of metastable Ca2IrO4 epitaxial thin-films: systematic comparison with Sr2IrO4 and Ba2IrO4
M. Souri, J. H. Gruenewald, J. Terzic +3
We have synthesized thermodynamically metastable Ca2IrO4 thin-films on YAlO3 (110) substrates by pulsed laser deposition. The epitaxial Ca2IrO4 thin-films are of K2NiF4-type tetrag…
Conducting LaAlO3/SrTiO3 heterointerfaces on atomically flat substrates prepared by deionized-water
J. G. Connell, J. Nichols, J. H. Gruenewald +2
We have investigated how the recently-developed water-leaching method for atomically-flat SrTiO3 (STO) substrates affects the transport properties of LaAlO3 (LAO) and STO heteroint…
Compressive strain-induced metal-insulator transition in orthorhombic SrIrO3 thin films
J. H. Gruenewald, J. Nichols, J. Terzic +3
We have investigated the electronic properties of epitaxial orthorhombic SrIrO3 thin-films under compressive strain. The metastable, orthorhombic SrIrO3 thin-films are synthesized…
Pulsed laser deposition with simultaneous in situ real-time monitoring of optical spectroscopic ellipsometry and reflection high-energy electron diffraction
J. H. Gruenewald, J. Nichols, S. S. A. Seo
We present a pulsed laser deposition (PLD) system that can monitor growth by simultaneously using in situ optical spectroscopic ellipsometry (SE) and reflection high-energy electro…
