Superconducting spintronics

Conventional superconductors are formed of antiparallel spin-paired electrons (singlet Cooper pairs, ↑↓) with zero net spin while ferromagnets with aligned spins are the key to spin-based electronics (spintronics).

Recently, a synergy between superconductivity and spintronics has been achieved by creating spin triplet Cooper pairs with aligned spins (↑↑ ­­or ↓↓) at the interface between a superconductor and a ferromagnet. The net spin of the superconductivity, in principle, creates a bridge between spintronics and superconducting electronics (superconducting spintronics). 

In the last few years, we have demonstrated radically novel ways to generate and control triplet Cooper pairs in multilayer ferromagnetic Josephson junctions (Nature Communications 5, 4771, 2014Figure 1), ability of ferromagnets to filter triplet Cooper pairs (Nature Communications 5, 3048, 2014) and triplet superconducting spin switches (Physical Review B, 89, 140508(R), 2014).

Our recent work (Physical Review B, 98, 144516, 2018 Figure 2) has identified a unique way to dynamically detect triplets. It shows that our present understanding of the dynamics of the triplet superconducting state is limited and opens the possibility for new theoretical models to describe the dynamics.

Superconducting spintronics figure 1
Figure 1:(a) At high magnetic fields, the ferromagnetic (F) layers are parallel and the combined F-layer thickness is much greater than the coherence length of the singlet Cooper pairs; no supercurrent flows through the structure. (b) At zero or low magnetic fields, the inhomogeneous or non-collinear F'layers converts the spin-singley Cooper pairs in S in to equal spin-triplet Cooper pairs in F thus allowing a finite triplet supercurrent to flow through the structure.

Spin-orbit coupling-driven superconducting spintronics

Superconducting spintronics, although attractive, has some serious challenges. The ↑↑ or ↓↓ triplet Cooper pairs are generated from ↑↓ singlet Cooper pairs by passing them through two ferromagnetic thin film (F1, F2) layers with non-collinear (ideally orthogonal) magnetisations. Maintaining non-collinear alignments is difficult, especially in nanoscale devices like Josephson junctions. Practical applications require a significantly simplified structure with fewer F layers and interfaces. 

The aim of this research theme is to demonstrate a radically different approach: generate and control triplet Cooper pairs by incorporating spin-orbit coupling (SOC) at the interface between a superconductor and a single homogeneous ferromagnet. This not only dramatically simplifies the structure, but opens an entirely new avenue in superconducting spintronics making it practically feasible. This builds on our recent results showing the controlled generation of triplet Cooper pairs in Nb/Pt/Co/Pt system (Physical Review B. 97, 184521, 2018Figure 1).

Figure 1. Critical temperature difference ∆Tc calculated between Nb/Pt/Co/Pt and Nb/Co/Pt as a function of in-and out-of-plane fields H. Top row shows the (a) experimental and (b) simulated ∆Tc for in-plane fields. Corresponding out-of-plane (c) experimental and (d) simulated ∆Tc are shown in the bottom row. Without spin-orbit coupling, ∆Tc should be zero in both cases.

Novel electronic and magnetic states in pyrochlore iridates

The interplay of electron correlations, band topology and frustration inpyrochlore iridates (R2Ir2O7, R= rare earths) gives rise to unique correlated electronic and magnetic states. With a broader aim to design multifunctional materials for energy efficient ultralow dissipative devices, we will study how these effects could be controllably tuned in thin films and the possibility to induce novel phases by application of pressure and interface it with other materials with radically different order parameters (like superconductors). This work is in collaboration with Prof. Subham Majumdar's group at the Indian Association for the Cultivation of Science, Kolkata.
