Spin-Transfer-Torque in ferro/nichtferromagnetischen Säulenstrukturen

open access: yes, 2010
In der vorliegenden Arbeit wird der Spin-Transfer-Torque-Effekt in säulenartigen ferro-/nichtferromagnetischen Schichtstrukturen untersucht. Durch ihn kann die Richtung der Magnetisierung allein mit Hilfe eines Stromes beeinflusst werden, was üblicherweise über den Riesenmagnetowiderstands-Effekt nachgewiesen wird.

Concealable and Field‐Free Physical Unclonable Function Based on Voltage‐Controlled Magnetic Tunnel Junctions

open access: yesAdvanced Electronic Materials, EarlyView.
A concealable physical unclonable function (PUF) based on an array of 384 nanoscale voltage‐controlled magnetic tunnel junctions is demonstrated. The PUF operates without any external magnetic field. It uses a combination of deterministic and stochastic switching mechanisms, based on the spin transfer torque and voltage‐controlled magnetic anisotropy ...

Spin Transfer Torques and Spin Fluctuations in Helimagnets

open access: yes, 2012
Two different aspects of the helimagnetic material systems MnSi and Mn1-xFexSi were treated. In the first part, spin transfer torques in MnSi were examined and in the second part spin fluctuations in pure MnSi and in Mn1-xFexSi. The influence of electric current on the magnetic structure in the skyrmion phase of MnSi was measured with small angle ...
