Journal ArticleDOI
Electric breakdown in ultra-thin MgO tunnel barrier junctions for spin-transfer torque switching
Markus Schäfers,Volker Drewello,Günter Reiss,Andy Thomas,K. Thiel,Gerrit Eilers,Markus Münzenberg,Henning Schuhmann,Michael Seibt +8 more
TL;DR: In this paper, the dielectric breakdown occurs typically at voltages not much higher than the switching voltages, a bottleneck for the implementation of spin-transfer torque Magnetic Random Access Memory.
Journal ArticleDOI
Direct imaging of the structural change generated by dielectric breakdown in MgO based magnetic tunnel junctions
Andy Thomas,Volker Drewello,Markus Schäfers,Alexander Weddemann,Günter Reiss,Gerrit Eilers,Markus Münzenberg,K. Thiel,Michael Seibt +8 more
TL;DR: In this article, the MgO barrier shows many microscopic pinholes after breakdown, which can be explained within a model assuming a relationship between the current density at the breakdown and the rate of pinhole formation.
Journal ArticleDOI
Spin-Transfer Torque Switching at Ultra Low Current Densities
Johannes Christian Leutenantsmeyer,Johannes Christian Leutenantsmeyer,Vladyslav Zbarsky,Vladyslav Zbarsky,Marvin von der Ehe,Steffen Wittrock,Patrick Peretzki,Henning Schuhmann,Andy Thomas,Karsten Rott,Günter Reiss,Tae Hee Kim,Michael Seibt,Markus Münzenberg +13 more
TL;DR: In this paper, the influence of the tantalum buffer layer on the magnetic anisotropy of perpendicular Co-Fe-B/MgO based magnetic tunnel junctions was studied using magneto-optical Kerr-spectroscopy.
Journal ArticleDOI
Magnetization dynamics in optically excited nanostructured nickel films
Georg M. Müller,Gerrit Eilers,Zhao Wang,Malte Scherff,Ran Ji,Kornelius Nielsch,Markus Münzenberg +6 more
TL;DR: In this article, the influence of the nanosize on the magnetization dynamics of nanostructured nickel films is investigated considering the time-scale of hundreds of femtoseconds as well as the GHz regime.
Journal ArticleDOI
Frequency‐Independent Terahertz Anomalous Hall Effect in DyCo5, Co32Fe68, and Gd27Fe73 Thin Films from DC to 40 THz
Tom Seifert,Tom Seifert,Ulrike Martens,Florin Radu,Mirkow Ribow,Marco Berritta,L. Nadvornik,R. Starke,Tomas Jungwirth,Tomas Jungwirth,Martin Wolf,Ilie Radu,Markus Münzenberg,Peter M. Oppeneer,Georg Woltersdorf,Tobias Kampfrath,Tobias Kampfrath +16 more
TL;DR: The anomalous Hall effect (AHE) is a fundamental spintronic charge-to-charge current conversion phenomenon and closely related to spin-tocharge-current conversion by the spin Hall effect as discussed by the authors.
