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…
Thermally-generated spin current in the topological insulator BiSe
Rakshit Jain, Max Stanley, Arnab Bose +6
We complete measurements of interconversions among the full triad of thermal gradients, charge currents, and spin currents in the topological insulator BiSe by quantifying…
Detection of long-range orbital-Hall torques
Arnab Bose, Fabian Kammerbauer, Rahul Gupta +4
We report and quantify a large orbital-Hall torque generated by Nb and Ru, which we identify from a strong dependence of torques on the ferromagnets. This is manifested as a sign r…
Origins of transverse voltages generated by applied thermal gradients and applied electric fields in ferrimagnetic-insulator/heavy-metal bilayers
Arnab Bose, Rakshit Jain, Jackson J. Bauer +3
We compare thermal-gradient-driven transverse voltages in ferrimagnetic-insulator/heavy-metal bilayers (Tm3Fe5O12/W and Tm3Fe5O12/Pt) to corresponding electrically-driven transvers…
Tilted spin current generated by the collinear antiferromagnet RuO2
Arnab Bose, Nathaniel J. Schreiber, Rakshit Jain +8
We report measurements demonstrating that when the Neel vector of the collinear antiferromagnet RuO2 is appropriately canted relative to the sample plane, the antiferromagnet gener…
Interfacial and bulk spin Hall contributions to field-like spin-orbit torque generated by Iridium
Sutapa Dutta, Arnab Bose, A. A. Tulapurkar +2
We present measurements of spin orbit torques generated by Ir as a function of film thickness in sputtered Ir/CoFeB and Ir/Co samples. We find that Ir provides a damping-like compo…
Role of Dirac nodal lines and strain on the high spin Hall conductivity of epitaxial IrO2 thin films
Arnab Bose, Jocienne N. Nelson, Xiyue S. Zhang +6
Since the discovery of a 'giant' spin Hall effect (SHE) in certain heavy metal elements there has been an intense effort to identify and develop new and technologically viable, hea…
Direct Observation of the Reciprocity between Spin Current and Phonon Interconversion
Swapnil Bhuktare, Hanuman Singh, Arnab Bose +1
Spin current has emerged as a leading candidate for manipulation of spins in a nano-magnet. We here experimentally show another utility of spin current viz. it can be used for gene…
Integer, fractional and side band injection locking of spintronic feedback nano-oscillator to microwave signal
Hanuman Singh, K. Konishi, S. Bhuktare +8
In this article we demonstrate the injection locking of recently demonstrated spintronic feedback nano oscillator to microwave magnetic fields at integers as well fractional multip…
Sign reversal of field like spin-orbit torque in ultrathin Chromium/Nickel bilayer
Arnab Bose, Hanuman Singh, Swapnil Bhuktare +2
In this work report unconventional sign change of field like spin orbit torque in ultra-thin Chromium(1.5nm-5nm)/Nickel(8nm) bi-layer. We performed standard spin-torque ferromagnet…
Observation of anomalous spin-torque generated by a ferromagnet
Arnab Bose, Duc Duong Lam, Swapnil Bhuktare +4
In this work we report observation of in-plane current induced out-of-plane magnetic field driven torque in spin valve structure. Since ferromagnet has high spin orbit coupling it…
Observation of Spin Nernst effect in Platinum
Arnab Bose, Swapnil Bhuktare, Hanuman Singh +2
Central focus of spintronics is concentrated on generation of pure spin current and associated spin torque. Pure spin current can be generated by spin Hall effect in heavy metals b…
Magneto-Seebeck effect in spin-valve with in-plane thermal gradient
S. Jain, D. D. Lam, A. Bose +5
We present measurements of magneto-Seebeck effect on a spin valve with in-plane thermal gradient. We measured open circuit voltage and short circuit current by applying a temperatu…
