Exchange-coupled structures consisting of ferromagnetic and ferrimagnetic layers become technologically more and more important. We show experimentally the occurrence of completely reversible, hysteresis-free minor loops of [Co(0.2 nm)/Ni(0.4 nm)/Pt(

We demonstrate high-resolution magneto-optical imaging using circularly-polarized high-harmonic radiation. We quantitatively map amplitude and phase of the x-ray magnetic circular dichroism at the Co M-edge using coherent diffractive imaging.

We demonstrate the first implementation of magnetic nanoscale imaging using high harmonic radiation. Out-of-plane magnetization patterns of worm-like domains in a Co/Pd multilayer are mapped via Fourier transform holography with circularly polarized

Nanosecond pulsed two-beam laser interference is used to generate two-dimensional temperature patterns on a magnetic thin film sample. We show that the original domain structure of a [Co/Pd] multilayer thin film changes drastically upon exceeding the

Pulsed two beam direct laser interference patterning (DLIP) is used to generate two-dimensional temperature patterns on a magnetic sample. In contrast to other methods like electron beam lithography, DLIP offers the possibility to pattern large areas

We demonstrate that a low-remanent sample magnetization MR is crucial for all-optical magnetic switching (AOS) in ferrimagnets and ferrimagnet heterostructures. MR may be devised by the composition of the material. However, it can also be controlled

Surface acoustic waves (SAWs) are optically excited in periodic nanomagnet arrays and drive the magnetization precession via magnetoelastic coupling. The frequency of this mechanically induced magnetic response is pinned at the SAW frequency over an

We observe all-optical switching (AOS) in ferrimagnetic Fe100−x Tb x alloy films below, above, and in samples without a magnetic compensation point. AOS is linked to a low remanent magnetization M R and associated with laser heating up to the Curie
