Rapid supercurrent decay in MnSi Josephson junctions
Arjun Sapkota, Kurt Lorenzen, Tyler Kuhn +6
Theoretical work predicts that Josephson junctions containing metallic altermagnetic barriers should display - transitions of the critical current as a function of both barri…
Large critical current density Josephson junctions with PdNi barriers
Arjun Sapkota, Pukar Sedai, Robert M. Klaes +3
We report large -state critical current densities, , in Nb/PdNi/Nb Josephson junctions at PdNi thicknesses near the first -state. We obser…
Magnetism and Spin Dynamics in Room-Temperature van der Waals Magnet FeGeTe
Laith Alahmed, Bhuwan Nepal, Juan Macy +12
Two-dimensional (2D) van der Waals (vdWs) materials have gathered a lot of attention recently. However, the majority of these materials have Curie temperatures that are well below…
Sub-Nanosecond Spin-Transfer Torque in an Ensemble of Superparamagnetic-Like Nanomagnets
Satoru Emori, Christoph Klewe, Jan-Michael Schmalhorst +14
Spin currents can exert spin-transfer torques on magnetic systems even in the limit of vanishingly small net magnetization, as is the case for antiferromagnets. Here, we experiment…
Magnetic domain wall substructures in Pt/Co/Ni/Ir multi-layers
Maxwell Li, Arjun Sapkota, Anish Rai +6
We examine the substructures of magnetic domain walls (DWs) in [Pt/(Co/Ni)/Ir] multi-layers using a combination of micromagnetic theory and Lorentz transmission electron mi…
Magnetic Damping in Epitaxial Fe Alloyed with Vanadium and Aluminum
David A. Smith, Anish Rai, Youngmin Lim +12
To develop low-moment, low-damping metallic ferromagnets for power-efficient spintronic devices, it is crucial to understand how magnetic relaxation is impacted by the addition of…
Formation of zero-field Skyrmion arrays in asymmetric superlattices
Maxwell Li, Anish Rai, Ashok Pokhrel +5
We demonstrate the formation of metastable Néel-type skyrmion arrays in Pt/Co/Ni/Ir multi-layers at zero-field following \textit{ex situ} application of an in-plane magnetic field…
Conductivity-Like Gilbert Damping due to Intraband Scattering in Epitaxial Iron
Behrouz Khodadadi, Anish Rai, Arjun Sapkota +15
Confirming the origin of Gilbert damping by experiment has remained a challenge for many decades, even for simple ferromagnetic metals. In this Letter, we experimentally identify G…
Magnetic domain wall Skyrmions
Ran Cheng, Maxwell Li, Arjun Sapkota +7
It is well established that the spin-orbit interaction in heavy metal/ferromagnet heterostructures leads to a significant interfacial Dzyaloshinskii-Moriya Interaction (DMI) that m…
