NONCOLLINEAR MAGNETIC ORDER IN THE DOUBLE PEROVSKITES: DOUBLE EXCHANGE ON A GEOMETRICALLY FRUSTRATED LATTICE
(2013)
Double perovskites (DPs) of the form A2BB′ O6 usually involve a transition metal ion, B, with a large magnetic moment, and a nonmagnetic ion B′. While many DPs are ferromagnetic, studies on the underlying model reveal the ...
Magnetic noise in MgO-based magnetic tunnel junction rings
(2010)
Magnetization switching is investigated in ring-shaped MgO-based magnetic tunnel junctions with
168% tunneling magnetoresistance. Besides the forward and reverse onion states, two vortex
states and several metastable ...
Oxidation of W(110) studied by LEED and STM
(2010)
The oxidation of W(110) was studied over a temperature a range of 1000 K to 1600 K at 1x10-6 Torr oxygen. The subsequent oxide structure was then characterized using Low Energy Electron Di_raction (LEED) and Scanning ...
Development of stiff, strong, yet tough composites by the addition of solvent exfoliated graphene to polyurethane
(2010)
We have prepared graphene dispersions, stabilised by polyurethane in tetrahydrofuran and dimethylformamide. These dispersions can be drop-cast to produce free-standing composite films. The graphene mass fraction is determined ...
Interfacial transport properties between a strongly correlated transition metal oxide and a metal: Contact resistance in Fe3O4/M (M=Cu, Au, Pt) nanostructures
(2010)
Multiterminal measurements have typically been employed to examine electronic properties of strongly correlated electronic materials such as transition metal oxides without the influence of contact effects. In contrast, ...
Self-assembled broadband plasmonic nanoparticle arrays for sensing applications
(2012)
Highly ordered noble metal nanoparticle (NP) arrays are produced using a glancing angle deposition on stepped substrates. The versatility of the technique is demonstrated by depositing different metals, resulting in shifts ...
Interface engineering of graphene nanosheet reinforced ZrB2 composites by tuning surface contacts
(American Physical Society (APS), 2019)
The mechanical properties of heterophase interfaces are critically important for the behavior of graphenereinforced
composites. In this work, the structure, adhesion, cleavage, and sliding of heterophase interfaces
formed ...

Rapid and Reliable Calibration of Laser Beam Deflection System for Microcantilever-Based Sensor Setups
(2012)
Cantilever array-based sensor devices widely utilise the laser-based optical deflection method for measuring static cantilever deflections mostly with home-built devices with individual geometries. In contrast to scanning ...
