Single device offset-free magnetic field sensing principle with tunable sensitivity and linear range based on spin-orbit-torques
Sabri Koraltan, Christin Schmitt, Florian Bruckner +12
We propose a novel device concept using spin-orbit-torques to realize a magnetic field sensor, where we eliminate the sensor offset using a differential measurement concept. We der…
Direct evidence of terahertz emission arising from anomalous Hall effect
V. Mottamchetty, P. Rani, R. Brucas +3
A detailed understanding of the different mechanisms being responsible for terahertz (THz) emission in ferromagnetic (FM) materials will aid in designing efficient THz emitters. In…
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…
Ultrafast magnetization dynamics in half-metallic CoFeAl Heusler alloy
R. S. Malik, E. K. Delczeg-Czirjak, D. Thonig +12
We report on optically induced, ultrafast magnetization dynamics in the Heusler alloy , probed by time-resolved magneto-optical Kerr effect. Experimental resul…
Impact of the crystal orientation on spin-orbit torques in Fe/Pd bilayers
Ankit Kumar, Nilamani Behera, Rahul Gupta +5
Spin-orbit torques in ferromagnetic (FM)/non-magnetic (NM) heterostructures offer more energy-efficient means to realize spin-logic devices; however, their strengths are determined…
Spin pumping and spin torque in interfacial tailored Co2FeAl/\b{eta}-Ta layers
Ankit Kumar, Rahul Gupta, Sajid Husain +5
The Heusler ferromagnetic (FM) compound Co2FeAl interfaced with a high-spin orbit coupling non-magnetic (NM) layer is a promising candidate for energy efficient spin logic circuits…
Engineering of spin mixing conductance in Ru/FeCo/Ru interfaces: Effect of Re Doping
Rahul Gupta, Nilamani Behera, Vijay A. Venugopal +6
We have deposited polycrystalline Re doped (0 x 12.6 at\%) thin films grown under identical conditions and sandwiched between thin la…
Direct Observation of Unusual Interfacial Dzyaloshinskii-Moriya Interaction in Graphene/NiFe/Ta Heterostructure
Avinash Kumar Chaurasiya, Akash Kumar, Rahul Gupta +3
Graphene/ferromagnet interface promises a plethora of new science and technology. The interfacial Dzyaloshinskii Moriya interaction (iDMI) is essential for stabilizing chiral spin…
