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…
