Spin torque driven mode hybridization and band engineering in nanopatterned magnonic crystals
Nikhil Kumar
Spin wave propagation and dynamic control are essential for reconfigurable magnonic and spintronic devices. Here, tunable mode coupling and band hybridisation are demonstrated in a…
Controlling hysteresis in superconducting constrictions with a resistive shunt
Nikhil Kumar, C. B. Winkelmann, Sourav Biswas +2
We demonstrate control of the thermal hysteresis in superconducting constrictions by adding a resistive shunt. In order to prevent thermal relaxation oscillations, the shunt resist…
Reversibility of Superconducting Nb Weak Links Driven by the Proximity Effect in a Quantum Interference Device
Nikhil Kumar, T. Fournier, H. Courtois +2
We demonstrate the role of proximity effect in the thermal hysteresis of superconducting constrictions. From the analysis of successive thermal instabilities in the transport chara…
Temperature and phase dynamics in superconducting weak-link
Anjan K. Gupta, Nikhil Kumar, Sourav Biswas
A time dependent thermal model for a superconducting constriction based weak-link (WL) is discussed for investigating the deterministic dynamics of its temperature and phase. A new…
