High-frequency magnetic characteristics are essential for improving the efficiency, miniaturization, and operating frequency ...

Stabilising curve: The arrows show the remnant magnetisation of a toroidal nanomagnet. On the outer edge (the right) we can see a vortex where the magnetisation spirals inwards to a point. An ...

Recently, observation of new topological magnetic structures represented by skyrmions is expected to provide new paths in constructing spintronic devices. In magnetic bubbles, although these are ...

Three-dimensional magnetic vortices have been discovered by scientists from the Helmholtz-Zentrum Dresden-Rossendorf in Germany together with colleagues from the Paul Scherrer Institute in Switzerland ...

Magnetometry exploiting color center defects in diamond probes and magneto-optic imaging have been found to complement each other. This supports progress towards the creation of more effective data ...

Physicists in Europe and the US have developed a new technique for reversing the "core polarization" of the tiny magnetic whirlpools that exist in certain materials. The reversal, which can be ...

Analyzing magnetic nanostructures with a high resolution is a test-and-measurement challenge, but it’s important for both advanced physics insight as well as real-world products such as high-density ...

Consequently, this energy transfer causes the rearrangement into a magnetic structure, which is stabilized by the subsequent rapid cooling. In follow-up experiments, the researchers aim to observe ...

To magnetize an iron nail, one simply has to stroke its surface several times with a bar magnet. Yet, there is a much more unusual method: A team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) ...
