Electron Transport and Dynamics in Magnetic and Superconducting Nanostructures
Current research lines
Organic, inorganic and superconducting spintronics: conductance, shot noise and 1/f noise
MAGNETRANS group is a leading Spanish and European
group with expertise in experimental studies of noise in magnetic and spintronic
structures. In 2006 we pioneered shot noise studies in magnetic tunnel junctions (in collaboration with group of Dr. Moodera, MIT, Boston, USA and prof. Y. Tserkovnyak, UCLA, USA). Our recent studies include the demonstration of
control over shot noise in double barrier magnetic tunnel junctions
(Cascales et al., PRL 2012) and band edge noise spectroscopy in spintronics
(Aliev et al., PRL 2014). Ongoing studies aim towards statistics of
tunneling through organic and superconducting barriers (Applied Physics Letters 105, 233302, 2014).
Microwave and nonlinear dynamics of superconducting vortex
MAGNETRANS
is a leading Spanish group in experimental studies and simulations of microwave
(GHz) complex dynamic response in type II superconductors. Our recent studies demonstrated the existence of multiple microwave superconducting vortex
depinning frequencies (Awad, et al. PRB2011). Our current studies include nonlinear
dynamics and losses of superconducting vortices (Lara et al. Scientific Reports 5, 9187, 2015).
Spin waves along topological anomalies
MAGNETRANS
is a leading Spanish group in experimental studies and simulations of spin
waves in magnetic nanostructures. Our very recent studies include the discovery of a new kind of spin waves which propagate along edges on magnetic
microstrucutures (Lara, et al. JAP 2013, SPIN2014).
Lateral photo and thermo effects in MOS structures
Since 2013
MAGNETRANS opened a new direction in the investigation of lateral photovoltaic
and thermoelectric effects in litographically patterned MOS structures (Applied Physical Letters 104, 231118, 2014).
