Reversible magneto ionics in crystallized W Co20Fe60B20 MgO HfO2 ultra-thin films with perpendicular magnetic anisotropy
Song Chen, Elmer Monteblanco, Benjamin Borie +2
We have investigated electric field (E-field) induced modulation of perpendicular magnetic anisotropy (PMA) in both amorphous and crystalline W/CoFeB/MgO/HfO2 ultra-thin films. We…
Tuning of perpendicular magnetic anisotropy in Bi-substituted yttrium iron garnet films by He ion irradiation
Sreeveni Das, Rhodri Mansell, Lukáš Flajšman +6
We report the continuous tuning of magnetic anisotropy in perpendicularly magnetized bismuth-substituted yttrium iron garnet (Bi-YIG) films via He ion irradiation. Our findings…
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…
