Influence of resistance and spin-torque bias dependence on the output power of MgO-based nano oscillators

Autor: Kowalska, E., Fukushima, A., Sluka, V., Fowley, C., Kákay, A., Aleksandrov, Y., Lindner, J., Fassbender, J., Yuasa, S., Deac, A. M.

Publikováno v: MMM 2017-62nd Annual Conference on Magnetism and Magnetic Materials, 06.-10.11.2017, Pittsburgh, USA

Spin-transfer torques (STTs) can be exploited in order to manipulate magnetic moments of nanomagnets, allowing for new consumer-oriented devices to be designed, such as tuneable radio-frequency spin-torque nano oscillators (STNOs) for wireless commun

Thermally Induced Spin Transfer Torque on MgO-based magnetic tunnel junctions using microstrip based resonator

Autor: Cansever, H., Fowley, C., Narkowicz, R., Kowalska, E., Aleksandrov, Y., Yildirim, O., Titova, A., Lenz, K., Lindner, J., Fassbender, J., Deac, A. M.

Publikováno v: DPG-Frühjahrstagung 2017, 19.-24.03.2017, Dresden, Germany

Magnetic tunnel junctions have been commonly used in spintronics applications, such as magnetic random access memory (M-RAM), spin transfer torque RAM (STT-RAM) and hard disc drive (HDD) because of high storage capacity. A spin polarized current flow

Investigating spin-transfer torques induced by thermal gradients on magnetic tunnel junctions using microcavity ferromagnetic resonance

Autor: Cansever, H., Fowley, C., Narkovic, R., Lenz, K., Kowalska, E., Yildirim, O., Aleksandrov, Y., Lindner, J., Fassbender, J., Deac, A. M.

Publikováno v: Magnetism and Magnetic Materials MMM 2017, 06.-10.11.2017, Pittsburgh, PA, USA

Similar to electrical currents flowing through magnetic multilayers [1], it has been predicted that thermal gradients applied across the spacer of a spin-valve or a magnetic tunnel junction may induce pure spin currents and generate ‘thermal’ spi

Magnetoresistive detection of single magnetic vortices

Autor: Ramasubramanian, L., Fowley, C., Kákay, A., Aleksandrov, Y., Matthes, P., Lindner, J., Fassbender, J., Gemming, S., Schulz, S., Deac, A.

Publikováno v: DPG Frühjahrstagung Regensburg 2016, 06.-11.03.2016, Regensburg, Germany

The fundamental oscillation mode of magnetic vortices in thin-film elements has recently been exploited in spin-torque-driven nano-oscillators [A. Wachowiak et al., Science (2002)]. The fundamental frequency is determined by the saturation magnetisat
