Magnetization dynamics driven by displacement currents across a magnetic tunnel junction

C. K. Safeer, Paul S. Keatley, Witold Skowroński +11

Understanding the high-frequency transport characteristics of magnetic tunnel junctions (MTJs) is crucial for the development of fast-operating spintronics memories and radio frequ…

Spin-torque Dynamics for Noise Reduction in Vortex-based Sensors

Mafalda Jotta Garcia, Julien Moulin, Steffen Wittrock +12

Performance of magnetoresistive sensors is today mainly limited by their 1/f low-frequency noise. Here, we study this noise component in vortex-based TMR sensors. We compare the no…

Influence of flicker noise and nonlinearity on the frequency spectrum of spin torque nano-oscillators

Steffen Wittrock, Philippe Talatchian, Sumito Tsunegi +12

The correlation of phase fluctuations in any type of oscillator fundamentally defines its spectral shape. However, in nonlinear oscillators, such as spin torque nano oscillators, t…

Low offset frequency flicker noise in spin torque vortex oscillators

Steffen Wittrock, Sumito Tsunegi, Kay Yakushiji +9

Low frequency noise close to the carrier remains little explored in spin torque nano oscillators. However, it is crucial to investigate as it limits the oscillator's frequency stab…
