Size-dependent enhancement of passive microwave rectification in magnetic tunnel junctions with perpendicular magnetic anisotropy
A. Sidi El Valli, V. Iurchuk, G. Lezier +11
Spintronic rf detectors were demonstrated, recently, for energy harvesting and wireless communication at low input power. Here we report on the optimization of the rectified output…
Ultra-fast GHz-range swept-tuned spectrum analyzer with 20 ns temporal resolution based on a spin-torque nano-oscillator with a uniformly magnetized 'free' layer
Artem Litvinenko, Ahmed Sidi El Valli, Vadym Iurchuk +5
The advantage of an ultra-fast frequency-tunability of spin-torque nano-oscillators (STNOs) that have large (> 100MHz) relaxation frequency of amplitude fluctuations is exploited t…
Mutual Synchronization of Spin-Torque Oscillators within a Ring Array
M. A. Castro, D. Mancilla-Almonacid, B. Dieny +3
An array of spin torque nano-oscillators (STNOs), coupled by dipolar interaction and arranged on a ring, has been studied numerically and analytically. The phase patterns and locki…
Target domains in nanometric Permalloy disks with columnar structure
Svetlana Ponomareva, Robert Morel, Hélène Joisten +2
We conducted a thorough experimental and numerical study of the micromagnetic properties of Permalloy (NiFe) microdisks exhibiting target domain structures at remanen…
Observation of magnetic helicoidal dichroism with extreme ultraviolet light vortices
Mauro Fanciulli, Matteo Pancaldi, Emanuele Pedersoli +17
We report on the experimental evidence of magnetic helicoidal dichroism, observed in the interaction of an extreme ultraviolet vortex beam carrying orbital angular momentum with a…
