A topological meron features a non-coplanar structure, whose order parameters in the core
region are perpendicular to those near the perimeter. A meron is half of a skyrmion, and both …

Racetrack memories with magnetic skyrmions have recently been proposed as a promising
storage technology. To be appealing, several challenges must still be faced for the …

A storage scheme based on racetrack memory, where the information can be coded in a
domain or a skyrmion, seems to be an alternative to conventional hard disk drive for high …

Understanding the physical properties of magnetic skyrmions is important for fundamental
research with the aim to develop new spintronic device paradigms where both logic and …

By analogy with spin waves in ferromagnetic systems, the polarization (or dipole) wave is
the electric counterpart that remains elusive. Here, we discover that the helielectricity, ie a …

Nonlinear dynamics has been the key ingredient to improve the performance, in terms of
sensitivity, of biased resonant spintronic diodes beyond their semiconductor counterparts …

The realization of terahertz (THz) sources is a fundamental aspect for a wide range of
applications. Over different approaches, compact THz oscillators can be realized, taking …

Magnetic skyrmions are particle-like topological spin configurations, which can carry binary
information and thus are promising building blocks for future spintronic devices. In this work …

This paper introduces the concept of spin–orbit-torque-magnetic random access memory
(SOT-MRAM) based physical unclonable function (PUF). The secret of the PUF is stored into …

We performed finite-element micromagnetic simulations to examine the formation of
skyrmions without intrinsic Dzyaloshinskii–Moriya interaction (DMI) in magnetic …
