Unexpected Termination Switching and Polarity Compensation in LaAlO3/SrTiO3 heterostructures
Guneeta Singh-Bhalla, Pim B. Rossen, Gunnar K. Palsson +12
Polar crystals composed of charged ionic planes cannot exist in nature without acquiring surface changes to balance an ever-growing dipole. The necessary changes can manifest struc…
Epitaxy-distorted spin-orbit Mott insulator in Sr2IrO4 thin films
C. Rayan Serrao, Jian Liu, J. T. Heron +14
High quality epitaxial thin films of Jeff=1/2 Mott insulator Sr2IrO4 with increasing in-plane tensile strain have been grown on top of SrTiO3(001) substrates. Increasing the in-pla…
Growth and characterization of multiferroic BiMnO thin films
Hyoungjeen Jeen, Guneeta Singh-Bhalla, Patrick R. Mickel +5
We have grown epitaxial thin films of multiferroic BiMnO using pulsed laser deposition. The films were grown on SrTiO (001) substrates by ablating a Bi-rich target. Using x…
Built-in and induced polarization across LaAlO/SrTiO heterojunctions
Guneeta Singh-Bhalla, Christopher Bell, Jayakanth Ravichandran +6
Ionic crystals terminated at oppositely charged polar surfaces are inherently unstable and expected to undergo surface reconstructions to maintain electrostatic stability. Essentia…
Tunneling magnetoresistance in (La,Pr,Ca)MnO3 nanobridges
G. Singh-Bhalla, A. Biswas, A. F. Hebard
The manganite (La,Pr,Ca)MnO3 is well known for its micrometer scale phase separation into coexisting ferromagnetic metallic and antiferromagnetic insulating (AFI) regions. Fabricat…
Intrinsic tunneling in phase separated manganites
G. Singh-Bhalla, S. Selcuk, T. Dhakal +2
We present evidence of direct electron tunneling across intrinsic insulating regions in sub-micrometer wide bridges of the phase separated ferromagnet (La,Pr,Ca)MnO. Upon cooli…
