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…
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…
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…
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…
