Zero-field dynamics stabilized by in-plane shape anisotropy in MgO-based spin-torque oscillators
Ewa Kowalska, Attila Kákay, Ciarán Fowley +4
Here we demonstrate numerically that shape anisotropy in MgO-based spin-torque nano-oscillators consisting of an out-of-plane magnetized free layer and an in-plane polarizer is nec…
Tunnel magnetoresistance angular and bias dependence enabling tuneable wireless communication
Ewa Kowalska, Akio Fukushima, Volker Sluka +7
Spin-transfer torques (STTs) can be exploited in order to manipulate the magnetic moments of nanomagnets, thus allowing for new consumer-oriented devices to be designed. Of particu…
Emission and Propagation of Multi-Dimensional Spin Waves with nanoscale wavelengths in Anisotropic Spin Textures
V. Sluka, T. Schneider, R. A. Gallardo +15
Spin waves offer intriguing novel perspectives for computing and signal processing, since their damping can be lower than the Ohmic losses in conventional CMOS circuits. For contro…
Ferromagnetic resonance linewidth in coupled layers with easy-plane and perpendicular magnetic anisotropies
Jun-Wen Xu, Volker Sluka, Bartek Kardasz +2
Magnetic bilayers with different magnetic anisotropy directions are interesting for spintronic appli- cations as they offer the possibility to engineer tilted remnant magnetization…
Antiferromagnetic resonance excited by oscillating electric currents
Volker Sluka
In antiferromagnetic materials the order parameter exhibits resonant modes at frequencies that can be in the terahertz range, making them interesting components for spintronic devi…
Spin transport and dynamics in all-oxide perovskite LaSrMnO/SrRuO bilayers probed by ferromagnetic resonance
Satoru Emori, Urusa S. Alaan, Matthew T. Gray +4
Thin films of perovskite oxides offer the possibility of combining emerging concepts of strongly correlated electron phenomena and spin current in magnetic devices. However, spin t…
Direct measurement of the magnetic anisotropy field in Mn--Ga and Mn--Co--Ga Heusler films
Ciarán Fowley, Siham Ouardi, Takahide Kubota +10
The static and dynamic magnetic properties of tetragonally distorted Mn--Ga based alloys were investigated. Static properties are determined in magnetic fields up to 6.5~T using SQ…
Quenched Slonczewski-Windmill in Spin-Torque Vortex-Oscillators
Volker Sluka, Attila Kákay, Alina M. Deac +3
We present a combined analytical and numerical study on double-vortex spin-torque nano-oscillators and describe a mechanism that suppresses the windmill modes. The magnetization dy…
Spin-Transfer Torque Induced Vortex Dynamics in Fe/Ag/Fe Nanopillars
Volker Sluka, Attila Kakay, Alina M. Deac +3
We report experimental and analytical work on spin-transfer torque induced vortex dynamics in metallic nanopillars with in-plane magnetized layers. We study nanopillars with a diam…
