Ultrafast Electron-Lattice Coupling Dynamics in VO2 and V2O3 Thin Films
Elsa Abreu, Stephanie N. Gilbert Corder, Sun Jin Yun +11
Ultrafast optical pump - optical probe and optical pump - terahertz probe spectroscopy were performed on vanadium dioxide (VO2) and vanadium sesquioxide (V2O3) thin films over a wi…
Characterization of Surface Electromagnetic Waves and Scattering on Infrared Metamaterial Absorbers
Wen-Chen Chen, Machhindra Koirala, Xianliang Liu +7
We report, for the first time, a full experimental and computational investigation of all possible light matter interactions on the surface of an infrared metamaterial absorber (MM…
VO2 nanosheets: controlling the THz properties through strain engineering
Elsa Abreu, Mengkun Liu, Jiwei Lu +5
We investigate far-infrared properties of strain engineered vanadium dioxide nanosheets through epitaxial growth on a (100)R TiO2 substrate. The nanosheets exhibit large uniaxial s…
Exchange Bias Induced by the Fe3O4 Verwey transition
J. de la Venta, M. Erekhinsky, Siming Wang +3
We present a study of the exchange bias in different configurations of V2O3 thin films with ferromagnetic layers. The exchange bias is accompanied by a large vertical shift in the…
Target bias voltage effect on properties of magnetic tunnel junctions by biased target ion beam deposition
Wei Chen, Dao N. H. Nam, Jiwei Lu +2
Magnetic tunnel junctions (MTJ) with AlOx barrier were fabricated by a deposition tool called Biased Target Ion Beam Deposition (BTIBD) using low energy ion source (0-50 eV) and vo…
Propagation of Exchange Bias in CoFe/FeMn/CoFe Trilayers
D. N. H. Nam, W. Chen, K. G. West +3
CoFe/FeMn, FeMn/CoFe bilayers and CoFe/FeMn/CoFe trilayers were grown in magnetic field and at room temperature. The exchange bias field depends strongly on the order of d…
