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 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…
