Revealing nanoscale disorder in W/CoFeB/MgO ultra-thin films using domain wall motion
Johannes Wilhelmus van der Jagt, Vincent Jeudy, André Thiaville +11
Disorder in ultra-thin magnetic films can significantly hinder domain wall motion. One of the main issues on the path towards efficient domain wall based devices remains the charac…
Key points in the determination of the interfacial Dzyaloshinskii-Moriya interaction from asymmetric bubble domain expansion
A. Magni, G. Carlotti, A. Casiraghi +18
Different models have been used to evaluate the interfacial Dzyaloshinskii-Moriya interaction (DMI) from the asymmetric bubble expansion method using magneto-optics. Here we invest…
Ion irradiation and implantation modifications of magneto-ionically induced exchange bias in Gd/NiCoO
Christopher J. Jensen, Alberto Quintana, Mamour Sall +5
Magneto-ionic control of magnetic properties through ionic migration has shown promise in enabling new functionalities in energy-efficient spintronic devices. In this work, we demo…
Multiple magneto-ionic regimes in Ta/CoFeB/HfO
R. Pachat, D. Ourdani, J. W. van der Jagt +11
In Ta/CoFeB/HfO2 stacks a gate voltage drives, in a nonvolatile way, the system from an underoxidized state exhibiting in-plane anisotropy (IPA) to an optimum oxidation level resul…
Tailoring interfacial effect in multilayers with Dzyaloshinskii-Moriya interaction by helium ion irradiation
A. Sud, S. Tacchi, D. Sagkovits +13
We show a method to control magnetic interfacial effects in multilayers with Dzyaloshinskii-Moriya interaction (DMI) using helium (He) ion irradiation. We report results from…
Bloch-to-Néel domain wall transition evinced through morphology of magnetic bubble expansion in Ta/CoFeB/MgO layers
Arianna Casiraghi, Alessandro Magni, Liza Herrera Diez +5
Ta/CoFeB/MgO trilayers with perpendicular magnetic anisotropy are often characterised by vanishing or modest values of interfacial Dzyaloshinskii-Moriya interaction (DMI), which re…
Tuning spin torque nano-oscillator nonlinearity using He+ irradiation
Sheng Jiang, Roman Khymyn, Sunjae Chung +6
We use He irradiation to tune the nonlinearity, , of all-perpendicular spin-torque nano-oscillators (STNOs) using the He fluence-dependent perpendicular magnet…
The nature of domain walls in ultrathin ferromagnets revealed by scanning nanomagnetometry
J. -P. Tetienne, T. Hingant, L. J. Martinez +13
The recent observation of current-induced domain wall (DW) motion with large velocity in ultrathin magnetic wires has opened new opportunities for spintronic devices. However, ther…
Manipulation of electrical and ferromagnetic properties of photo-sensitized (Ga,Mn)As
L. Herrera Diez, M. Konuma, E. Placidi +6
We present the manipulation of magnetic and electrical properties of (Ga,Mn)As by the adsorption of dye-molecules as a first step towards the realization of light-controlled magnet…
Temperature dependent Neel wall dynamics in GaMnAs/GaAs
J. Honolka, L. Herrera Diez, R. K. Kremer +3
Extensive Kerr microscopy studies reveal a strongly temperature dependent domain wall dynamics in Hall-bars made from compressively strained GaMnAs. Depending on the temperature ma…
