Control of domain wall and pinning disorder interaction by light He ion irradiation in Pt/Co/AlOx ultrathin films

Cristina Balan, Johannes W. van der Jagt, Jose Peña Garcia +6

We have studied the effect of He irradiation on the dynamics of chiral domain walls in Pt/Co/AlOx trilayers in the creep regime. The irradiation leads to a strong decrease of t…

Improving Néel domain walls dynamics and skyrmion stability using He ion irradiation

Cristina Balan, Johannes W. van der Jagt, Aymen Fassatoui +8

Magnetization reversal and domain wall dynamics in Pt/Co/AlOx trilayers have been tuned by He+ ion irradiation. Fluences up to 1.5x10 ions/cm strongly decrease the perpe…

Optimization of Permalloy properties for magnetic field sensors using He irradiation

Giovanni Masciocchi, Johannes Wilhelmus van der Jagt, Maria-Andromachi Syskaki +7

Permalloy, despite being a widely utilized soft magnetic material, still calls for optimization in terms of magnetic softness and magnetostriction for its use in magnetoresistive s…

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…

Enhancing All-Optical Switching of Magnetization by He Ion Irradiation

Pingzhi Li, Johannes W. van der Jagt, Maarten Beens +8

All-optical switching (AOS) of magnetization by a single femtosecond laser pulse in Co/Gd based synthetic ferrimagnets is the fastest magnetization switching process. On the other…

Control of magnetoelastic coupling in Ni/Fe multilayers using He ion irradiation

Giovanni Masciocchi, Johannes Wilhelmus van der Jagt, Maria-Andromachi Syskaki +10

This study reports the effects of post-growth He irradiation on the magneto-elastic properties of a / multi-layered stack. The progressive intermixing caused by He
