Field and temperature-driven magnetic reversal of spin-flop coupled epitaxial Fe/MnPd bilayers

“…Similar scenarios have been reported in collinear systems 8,42,43 . By using x-ray magnetic dichroism, it was shown that both the unidirectional reversal characteristic and higher-order anisotropies can be present without the observation of the loop shift 8,44 .…”

Multiple in-plane spin reorientation transitions inFe/CoObilayers grown on vicinalMgO(001)

“…AFM spins in a CoO film grown on a MgO(001) flat surface prefer an in-plane direction with a strong four-fold anisotropy and the easy axis (EA) along the CoO<110> direction [23]. Because of spin-flopping coupling [24,25], field cooling in a Fe/CoO/MgO(001) system can induce a strong uniaxial anisotropy in the Fe film with the EA along the CoO<110> direction, which is close to the direction of the cooling field (H FC ), and with CoO AFM spins aligned perpendicular to H FC [26].…”

“…For an H FC that points in a direction perpendicular to the steps, one in-plane SRT of Fe moments was found around the T N of the CoO film. However, for an H FC direction parallel to the steps, we found two temperature-driven SRTs, and three CoO-thickness-driven SRTs [13,26]. Finally, the sample was capped by a 3 nm MgO layer, which was used as a protective layer for MOKE measurements.…”

Anomalous magneto-optical behavior of uniaxial Co/CoO bilayer films

“…Magneto-Optics has been also utilized to develop well-established technologies like MO recording [2], optical isolators [3,4], as well as novel applications within a wide range of different fields. Only the most recent ones alone cover topics from biosensing [5][6][7], magnetoplasmonics [8], nanomagnetism [9,10], ultrafast magnetization dynamics [11][12][13], magnetization reversal processes [14][15][16], to the anomalous behavior arising from the exchange bias effect [17][18][19][20], for instance.…”
