SP-STM study of the multi-Q phases in GdRu2Si2
Jonas Spethmann, Nguyen Duy Khanh, Haruto Yoshimochi +6
The two stable surfaces of GdRu2Si2 are studied using spin-polarized scanning tunneling microscopy (SP-STM). Depending on the applied magnetic field different magnetic phases have…
Phase Coexistence of Mn Trimer Clusters and Antiferromagnetic Mn Islands on Ir(111)
Arturo Rodríguez-Sota, Vishesh Saxena, Jonas Spethmann +4
Clusters supported by solid substrates are prime candidates for heterogeneous catalysis and can be prepared in various ways. While mass-selected soft-landing methods are often used…
Zero-field skyrmionic states and in-field edge-skyrmions induced by boundary tuning
Jonas Spethmann, Elena Y. Vedmedenko, Roland Wiesendanger +2
When magnetic skyrmions are moved via currents, they do not strictly travel along the path of the current, instead their motion also gains a transverse component. This so-called sk…
Domain Walls in a Row-Wise Antiferromagnetic Mn Monolayer
Jonas Spethmann, Martin Grünebohm, Roland Wiesendanger +2
We investigate magnetic domain walls in a single fcc Mn layer on Re(0001) employing spin-polarized STM, atom manipulation, and spin dynamics simulations. The low symmetry of the ro…
Discovery of magnetic single- and triple-Q states in Mn/Re(0001)
Jonas Spethmann, Sebastian Meyer, Kirsten von Bergmann +3
We experimentally verify the existence of two model-type magnetic ground states which were previously predicted but so far unobserved. We find them in Mn monolayers on the Re(0001)…
