Unlocking ultrafast spin dynamics in a rare-earth magnet
Paul Herrgen, Christian Holzmann, Torben Manzke +5
The speed of optically driven magnetization dynamics is fundamentally determined by how efficiently angular momentum can be transferred between electronic, spin and lattice degrees…
Dynamic interfacial effects in ultrathin ferromagnetic bilayers
Anulekha De, Christopher Seibel, Sanjay Ashok +7
We investigate the magnetization dynamics of an ultrathin Co (1.5 nm) /Py (1.5 nm) bilayer system from femtosecond (fs) to nanosecond (ns) timescales. Magnetization dynamics in the…
All optical excitation of spin polarization in d-wave altermagnets
Marius Weber, Stephan Wust, Luca Haag +14
The recently discovered altermagnets exhibit collinear magnetic order with zero net magnetization but with unconventional spin-polarized d/g/i-wave band structures, expanding the k…
Laser-induced Creation of antiferromagnetic 180-degree domains in NiO/Pt bilayers
Hendrik Meer, Stephan Wust, Christin Schmitt +15
We demonstrate how the antiferromagnetic order in heterostructures of NiO/Pt thin films can be modified by optical pulses. We irradiate our samples with laser light and identify an…
Indirect optical manipulation of the antiferromagnetic order of insulating NiO by ultrafast interfacial energy transfer
Stephan Wust, Christopher Seibel, Hendrik Meer +14
We report the ultrafast, (sub)picosecond reduction of the antiferromagnetic order of the insulating NiO thin film in a Pt/NiO bilayer. This reduction of the antiferromagnetic order…
