Thermal effects in spin torque switching of perpendicular magnetic tunnel junctions at cryogenic temperatures
Laura Rehm, Georg Wolf, Bartek Kardasz +4
Temperature plays an important role in spin torque switching of magnetic tunnel junctions causing magnetization fluctuations that decrease the switching voltage but also introduce…
Sub-nanosecond spin-torque switching of perpendicular magnetic tunnel junction nanopillars at cryogenic temperatures
Laura Rehm, Georg Wolf, Bartek Kardasz +2
Spin-transfer magnetic random access memory is of significant interest for cryogenic applications where a persistent, fast, low-energy consumption and high device density is needed…
Reduced Exchange Interactions in Magnetic Tunnel Junction Free Layers with Insertion Layers
Jamileh Beik Mohammadi, Bartek Kardasz, Georg Wolf +3
Perpendicularly magnetized CoFeB layers with ultra-thin non-magnetic insertion layers are very widely used as the electrodes in magnetic tunnel junctions for spin transfer magnetic…
Time-Resolved Studies of the Spin-Transfer Reversal Mechanism in Perpendicularly Magnetized Magnetic Tunnel Junctions
Christian Hahn, Georg Wolf, Bartek Kardasz +3
Pulsed spin-torque switching has been studied using single-shot time-resolved electrical measurements in perpendicularly magnetized magnetic tunnel junctions as a function of pulse…
Quasistatic and Pulsed Current-Induced Switching with Spin-Orbit Torques in Ultrathin Films with Perpendicular Magnetic Anisotropy
Yu-Ming Hung, Laura Rehm, Georg Wolf +1
Spin-orbit interaction derived spin torques provide a means of reversing the magnetization of perpendicularly magnetized ultrathin films with currents that flow in the plane of the…
Bipolar switching in an orthogonal spin transfer spin valve device
Li Ye, Georg Wolf, Daniele Pinna +2
We demonstrate current-induced bipolar switching in in-plane magnetized spin-valve devices that incorporate a perpendicularly magnetized spin polarizing layer. Further, hysteretic…
Temperature dependence of the switching field distributions in all-perpendicular spin-valve nanopillars
D. B. Gopman, D. Bedau, G. Wolf +4
We present temperature dependent switching measurements of the Co/Ni multilayered free element of 75 nm diameter spin-valve nanopillars. Angular dependent hysteresis measurements a…
Mode conversion by symmetry breaking of propagating spin waves
P. Clausen, K. Vogt, H. Schultheiss +6
We study spin-wave transport in a microstructured Ni81Fe19 waveguide exhibiting broken translational symmetry. We observe the conversion of a beam profile composed of symmetric spi…
