Temperature Evolution of Itinerant Ferromagnetism in SrRuO3 Probed by Optical Spectroscopy
D. W. Jeong, Hong Chul Choi, Choong H. Kim +12
The temperature () dependence of the optical conductivity spectra of a single crystal SrRuO thin film is studied over a range from 5 to 450 K. We observed signifi…
Room-Temperature Electronically-Controlled Ferromagnetism at the LaAlO3/SrTiO3 Interface
Feng Bi, Mengchen Huang, Chung-Wung Bark +4
Reports of emergent conductivity, superconductivity, and magnetism at oxide interfaces have helped to fuel intense interest in their rich physics and technological potential. Here…
Transmittance and reflectance measurements at terahertz frequencies on a superconducting BaFe_{1.84}Co_{0.16}As_2 ultrathin film: an analysis of the optical gaps in the Co-doped BaFe_2As_2 pnictide
Andrea Perucchi, Leonetta Baldassarre, Boby Joseph +7
Here we report an optical investigation in the terahertz region of a 40 nm ultrathin BaFeCoAs superconducting film with superconducting transition temperature…
Anomalous Transport in Sketched Nanostructures at the LaAlO3/SrTiO3 Interface
Guanglei Cheng, Joshua P. Veazey, Patrick Irvin +10
The oxide heterostructure LaAlO3/SrTiO3 supports a two-dimensional electron liquid with a variety of competing phases including magnetism, superconductivity and weak antilocalizati…
Electro-Mechanical Response of Top-Gated LaAlO3/SrTiO3 Heterostructures
Feng Bi, Mengchen Huang, Chung Wung Bark +5
LaAlO3/SrTiO3 heterostructures are known to exhibit a sharp, hysteretic metal-insulator transition (MIT) with large enhanced capacitance near depletion. To understand the physical…
