Journal ArticleDOI
Ultrafast Sweep-Tuned Spectrum Analyzer with Temporal Resolution Based on a Spin-Torque Nano-Oscillator.
A. N. Litvinenko,V. Iurchuk,Pankaj Sethi,Steven Louis,Vasyl Tyberkevych,Jia Li,A. S. Jenkins,Ricardo Ferreira,Bernard Dieny,Andrei Slavin,Ursula Ebels +10 more
TL;DR: It is shown that this STNO-based spectrum analyzer can perform analysis of frequency-agile signals, having multiple rapidly changing frequency components with temporal resolution in a μs time scale and frequency resolution limited only by the "bandwidth" theorem.
Journal ArticleDOI
Reconfigurable logic via gate controlled domain wall trajectory in magnetic network structure
TL;DR: This work presents a reconfigurable magnetic logic device which is capable of performing all basic logic operations in a single device and exploits the deterministic trajectory of domain wall in ferromagnetic asymmetric branch structure for obtaining different output combinations.
Journal ArticleDOI
Role of RKKY torque on domain wall motion in synthetic antiferromagnetic nanowires with opposite spin Hall angles.
Sachin Krishnia,Pankaj Sethi,Weiliang Gan,Farhan Nur Kholid,I. Purnama,M. Ramu,Tun Seng Herng,Jun Ding,Wen Siang Lew +8 more
TL;DR: The effect of enhanced spin-orbit and RKKY induced torques on the current-induced motion of a pair of domain walls (DWs), which are coupled antiferromagnetically in syntheticantiferromagnetic (SAF) nanowires, is experimentally shown.
Journal ArticleDOI
Bi-directional high speed domain wall motion in perpendicular magnetic anisotropy Co/Pt double stack structures
Pankaj Sethi,Sachin Krishnia,Weiliang Gan,Farhan Nur Kholid,Farhan Nur Kholid,Funan Tan,Ramu Maddu,Wen Siang Lew +7 more
TL;DR: Bi-directional domain wall (DW) motion along and against current flow direction in Co/Pt double stack wires with Ta capping is reported to improve its thermal stability and perpendicular magnetic anisotropy.
Journal ArticleDOI
Modulation of spin-orbit torque efficiency by thickness control of heavy metal layers in Co/Pt multilayers
TL;DR: In this article, the spin-orbit torque (SOT) strength by current induced effective in-plane magnetic fields and spin Hall angle (SHA) using AC harmonic Hall voltage measurements techniques was investigated and quantified.
