Fluctuation-mediated spin-orbit torque enhancement in the noncollinear antiferromagnet Mn3Ni0.35Cu0.65N
Arnab Bose, Tom G. Saunderson, Aga Shahee +9
The role of spin fluctuations near magnetic phase transitions is crucial for generating various exotic phenomena, including anomalies in the extraordinary Hall effect, excess spin-…
Higher-order Hall response arises from octupole order and scalar spin chirality in a noncollinear antiferromagnet
Adithya Rajan, Tom G. Saunderson, Fabian R. Lux +19
Noncollinear antiferromagnets can generate a transverse electrical response known as the anomalous Hall effect, even though they possess almost no net magnetization. The microscopi…
Mechanism of electrical switching of ultra-thin CoO/Pt bilayers
Christin Schmitt, Adithya Rajan, Grischa Beneke +9
We study current-induced switching of the Néel vector in CoO/Pt bilayers to understand the underlaying antiferromagnetic switching mechanism. Surprisingly, we find that for ultra-t…
Electric-field control of spin-orbit torques in perpendicularly magnetized W/CoFeB/MgO films
Mariia Filianina, Jan-Philipp Hanke, Kyujoon Lee +5
Controlling magnetism by electric fields offers a highly attractive perspective for designing future generations of energy-efficient information technologies. Here, we demonstrate…
