Antiferromagnetic single-layer spin-orbit torque oscillators
(2019)We show how a charge current through a single antiferromagnetic layer can excite and control self-oscillations. Sustained oscillations with tunable amplitudes and frequencies are possible in a variety of geometries using ... -
Au4Mn: A localized ferromagnet with strong spin-orbit coupling, long-rangeferromagnetic exchange, and high Curie temperature
(2022)Metallic Mn-based alloys with a nearest-neighbor Mn-Mn distance greater than 0.4 nm exhibit large, well-localized magnetic moments. Here we investigate the magnetism of tetragonal Au 4 Mn with a Curie temperature of ... -
Broadband saturable absorption and exciton-exciton annihilation in MoSe2 composite thin films
(2019)Polyvinyl alcohol (PVA) was utilized as a matrix to host two-dimensional (2D) liquid-phase-exfoliated MoSe2 nanosheets. These 2D MoSe2/PVA composite thin films were experimentally proven to be preferable for efficient ... -
Charge-modulated self-assembly and growth of conjugated polyelectrolyte-polyoxometalate hybrid networks.
(2014)Self-assembly of an anionic polyoxometalate with cationic conjugated polyelectrolytes leads to hybrid supramolecular networks whose dimensionality is controlled by the chain length and steric charge distribution. -
Co-percolation to tune conductive behaviour in dynamical metallic nanowire networks
(2016)Nanowire networks act as self‐healing smart materials, whose sheet resistance can be tuned via an externally applied voltage stimulus. This memristive response occurs due to modification of junction resistances to form a ... -
Conducting mechanism in the epitaxial p-type transparent conducting oxide Cr2O3:Mg
(2015)Epitaxial p -type transparent conducting oxide (TCO) Cr 2 O 3 :Mg was grown by electron-beam evaporation in a molecular beam epitaxy system on c -plane sapphire. The influence of Mg dopants and the oxygen partial ... -
Continuous wafer-scale graphene on cubic-SiC(001
(2013)The atomic and electronic structure of graphene synthesized on commercially available cubic-SiC(001)/Si(001) wafers have been studied by low energy electron microscopy (LEEM), scanning tunneling microscopy (STM), low energy ... -
Deformation and necking of liquid droplets in a magnetic field.
(2022)Pendant droplets of water and paramagnetic solutions are studied in the presence of uniform and nonuniform magnetic fields produced by small permanent magnet arrays, both in static conditions and during dynamic pinch-off. ... -
Detection of the Faraday Chiral Anisotropy
(2021)Being the intimate connection between chirality and magnetism, magneto-chiral anisotropies (MChA) - featuring non-reciprocal optical responses in chiral systems depending on the relative direction of the magnetic field B ... -
Development of SIRT1 siRNA-carrying liposomes for treatment of prostate cancer
(2020)Sirtuin 1 (SIRT1) is a histone deacetylase (HDAC) from Sirtuin family and high expression of it induces activation of DNA repairing factors eventually leading either tumor suppression or tumor development in cellular ... -
Effect of insertion layer on electrode properties in magnetic tunnel junctions with a zero-moment half-metal
(2019)Due to its negligible spontaneous magnetization, high spin polarization and giant perpendicular magnetic anisotropy, Mn2RuxGa (MRG) is an ideal candidate as an oscillating layer in THz spin-transfertorque nano-oscillators. ... -
