SQUID-detected FMR: Resonance in single crystalline and polycrystalline yttrium iron garnet
(2018)Here two new techniques for the detection of broadband (100 MHz–20 GHz) ferromagnetic resonance Here two new techniques for the detection of broadband (100 MHz–20 GHz) ferromagnetic resonance (FMR)/ferrimagnetic resonance ... -
Stability and capping of magnetite ultra-thin films
(2014)Ultrathin films of Fe3O4 have been grown epitaxially on nearly lattice matched MgO(001). The stability of 4 nm thick films in ambient air and under annealing in an oxygen atmosphere at 200◦C has been studied. By magneto ... -
Stability maps for columnar structures
(2023)We have previously explored the hysteresis and reversibility of transitions between ordered packings of soft spheres of diameter d in cylindrical channels of diameter D [A. Mughal, J. Winkelmann, D. Weaire, S. Hutzler, ... -
Stability of Mn2RuxGa-based multilayer stacks
(2022)Perpendicular heterostructures based on a ferrimagnetic Mn2RuxGa (MRG) layer and a ferromagnetic Co/Pt multilayer were examined to understand the effects of different spacer layers (V, Mo, Hf, HfOx and TiN) on the interfaces ... -
Stability of Mn2RuxGa-based Multilayer Stacks, Gwenaël Atcheson, Katarzyna Siewierska, J. M. D. Coey, Karsten Rode, Plamen Stamenov
(2022)Perpendicular heterostructures based on a ferrimagnetic Mn2RuxGa (MRG) layer and a ferromagnetic Co/Pt multilayer were examined to understand the effects of different spacer layers (V, Mo, Hf, HfOx and TiN) on the interfaces ... -
Stabilizing effect of a magnetic field on a gas bubble produced at a microelectrode
(2012)The effect on the growth of a single hydrogen bubble of a magnetic field oriented normal to the surface of a microelectrode is investigated. Overpotential oscillations due to periodic growth and detachment of bubbles are ... -
Star-planet interactions: I. Stellar rotation and planetary orbits
(2016)Context. As a star evolves, planet orbits change over time owing to tidal interactions, stellar mass losses, friction and gravitational drag forces, mass accretion, and evaporation on/by the planet. Stellar rotation modifies ... -
Star-planet interactions: II. is planet engulfment the origin of fast rotating red giants?
(2016)Context. Fast rotating red giants in the upper part of the red giant branch have surface velocities that cannot be explained by single star evolution. Aims. We check whether tides between a star and a planet followed ... -
Statistical distribution of the electric field-driven switching of the verwey state in Fe 3O 4
(2012)The insulating state of magnetite (Fe3O4) can be disrupted by a sufficiently large dc electric field. Pulsed measurements are used to examine the kinetics of this transition. Histograms of the switching voltage show a ... -
Steady states of a chi(3) parametric oscillator with coupled polarizations
(2003)Polarization effects in the microcavity parametric oscillator are studied using a simple model in which two x3 optical parametric oscillators are coupled together. It is found that there are, in general, a number of ... -
Steady-State Drainage of an Aqueous Foam
(American Physical Society, 1993)The process of wetting of a monodisperse foam by the continuous addition of liquid from the top has been investigated for a cylindrical column. The velocity of the interface between dry and wet foam was found to vary as ... -
Steps toward determination of the size and structure of the broad-line region in active galactic nuclei. XI. Intensive monitoring of the ultraviolet spectrum of NGC 7469
(American Institute of Physics, 1997)From 1996 June 10 to July 29, the International Ultraviolet Explorer monitored the Seyfert 1 galaxy NGC 7469 continuously in an attempt to measure time delays between the continuum and emission-line fluxes. From the time ... -
Steps toward determination of the size and structure of the broad-line region in active galatic nuclei. 8: an intensive HST, IUE, and ground-based study of NGC 5548
(1995)We present the data and initial results from a combined Hubble Space Telescope (HST)/IUE/ground-based spectroscopic monitoring campaign on the Seyfert 1 galaxy NGC 5548 that was undertaken in order to address questions ... -
Stiffness and atomic-scale friction in superlubricant MoS<sub>2</sub> bilayers
(2023)By using ab-initio-accurate force fields and molecular dynamics simulations we demonstrate that the layer stiffness has profound effects on the superlubricant state of two-dimensional van der Waals heterostructures. These ... -
Stimulated spin dynamics of polaritons in semiconductor microcavities
(American Physical Society, 2002)Time-resolved polarization spectroscopy of polariton pair scattering in semiconductor microcavities enables complete measurement of the polariton spin dynamics. In addition to spin-preserving interactions previously reported, ... -

Strain effects in spinel ferrite thin films from first principles calculations
(2011)The inverse spinel ferrimagnets CoFe2O4 (CFO) and NiFe2O4 (NFO) are of interest for applications in spin-filter devices or as building blocks of artificial multiferroic heterostructures. Here we present density functional ...
