Control of magnetization reversal processes is a key issue for the implementation of
magnetic materials in technological applications. The modulation of shape magnetic
anisotropy in nanowire structures with a high aspect ratio is an efficient way to tune sharp in‐
plane magnetic switching. However, control of fast magnetization reversal processes
induced by perpendicular magnetic fields is much more challenging. Here, tunable sharp
magnetoresistance changes, triggered by out‐of‐plane magnetic fields, are demonstrated in …

In article number 2200042, Alejandro V. Silhanek, Anna Palau, and co-workers study
permalloy strips with substrate-induced uniaxial anisotropy since they offer the possibility to
produce fast in-plane magnetization reversals triggered by an out-of-plane magnetic field.
Sharp magnetoresistance jumps tailored by the shape anisotropy of the strips are obtained
and are potentially useful for sensing and advanced magnetoresistive devices.
