Control of hidden ground-state order in NdNiO superlattices
Ankit S. Disa, Alexandru B. Georgescu, James L. Hart +8
The combination of charge and spin degrees of freedom with electronic correlations in condensed matter systems leads to a rich array of phenomena, such as magnetism, superconductiv…
Structural Distortions At Polar Manganite Interfaces
S. Koohfar, A. S. Disa, M. Marshall +3
Electronic, lattice, and spin interactions at the interfaces between crystalline complex transition metal oxides can give rise to a wide range of functional electronic and magnetic…
Experimental verification of orbital engineering at the atomic scale: charge transfer and symmetry breaking in nickelate heterostructures
Patrick J. Phillips, Paolo Longo, Alexandru B. Georgescu +7
Epitaxial strain, layer confinement and inversion symmetry breaking have emerged as powerful new approaches to control the electronic and atomic-scale structural properties in comp…
Hysteretic electrical transport in BaTiO/BaSrTiO/Ge heterostructures
J. H. Ngai, D. P. Kumah, C. H. Ahn +1
We present electrical transport measurements of heterostructures comprised of BaTiO and BaSrTiO epitaxially grown on Ge. The Sr-alloying imparts compressive str…
Angular dependence of the Hall effect of lsmo films
Netanel Naftalis, Noam Haham, Jason Hoffman +3
We find that the Hall effect resistivity () of thin films of \lsmo\ varies as a function of the angle between the applied magnetic field and the film normal as $ρ_{xy}=…
Thermal quench effects on ferroelectric domain walls
Patrycja Paruch, Alejandro B. Kolton, Xia Hong +2
Using piezoresponse force microscopy on epitaxial ferroelectric thin films, we have measured the evolution of domain wall roughening as a result of heat-quench cycles up to 735C, w…
Scanning SQUID Susceptometry of a paramagnetic superconductor
J. R. Kirtley, B. Kalisky, J. A. Bert +8
Scanning SQUID susceptometry images the local magnetization and susceptibility of a sample. By accurately modeling the SQUID signal we can determine the physical properties such as…
Resonant phonon coupling across the La{1-x}Sr{x}MnO{3}/SrTiO{3} interface
Y. Segal, K. F. Garrity, C. A. F. Vaz +4
The transport and magnetic properties of correlated La{0.53}Sr{0.47}MnO{3} ultrathin films, grown epitaxially on SrTiO{3}, show a sharp cusp at the structural transition temperatur…
Unusual Resistance Hysteresis in n-Layer Graphene Field Effect Transistors Fabricated on Ferroelectric Pb(Zr_0.2Ti_0.8)O_3
X. Hong, J. Hoffman, A. Posadas +3
We have fabricated n-layer graphene field effect transistors on epitaxial ferroelectric Pb(Zr_0.2Ti_0.8)O_3 (PZT) thin films. At low gate voltages, PZT behaves as a high-k dielectr…
Origin of the magnetoelectric coupling effect in Pb(Zr0.2Ti0.8)O3/La0.8Sr0.2MnO3 multiferroic heterostructures
C. A. F. Vaz, J. Hoffman, Y. Segal +5
The electronic valence state of Mn in Pb(Zr0.2Ti0.8)O3/La0.8Sr0.2MnO3 multiferroic heterostructures is probed by near edge x-ray absorption spectroscopy as a function of the ferroe…
Epitaxial Growth of Multiferroic YMnO3 on GaN
A. Posadas, J. -B. Yau, J. Han +5
In this work, we report on the epitaxial growth of multiferroic YMnO3 on GaN. Both materials are hexagonal with a nominal lattice mismatch of 4%, yet x-ray diffraction reveals an u…
