Role of substrate clamping on anisotropy and domain structure in the canted antiferromagnet -FeO
Angela Wittmann, Olena Gomonay, Kai Litzius +19
Antiferromagnets have recently been propelled to the forefront of spintronics by their high potential for revolutionizing memory technologies. For this, understanding the formation…
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…
Spin Dynamics, Loop Formation and Cooperative Reversal in Artificial Quasicrystals with Tailored Exchange Coupling
Vinayak Shantaram Bhat, Sho Watanabe, Florian Kronast +2
Aperiodicity and un-conventional rotational symmetries allow quasicrystalline structures to exhibit unprecedented physical and functional properties. In magnetism, artificial ferro…
Strain-induced Shape Anisotropy in Antiferromagnetic Structures
Hendrik Meer, Olena Gomonay, Christin Schmitt +9
We demonstrate how shape-induced strain can be used to control antiferromagnetic order in NiO/Pt thin films. For rectangular elements patterned along the easy and hard magnetocryst…
