I will provide an introduction to the field of research usually referred to as superconducting spintronics. First, I will discuss, in a general manner, how the interaction between superconductivity and spin-dependent fields leads to the emergence of unconventional superconducting states with Cooper pairs in a triplet state capable of carrying spin.
In the second part, I will discuss recent advances in understanding magnetoelectric effects in superconductors, similar to those observed in non-superconducting systems. I will emphasize the role of symmetry in predicting the effects of charge-spin conversion, and I will introduce the superconducting diode effect closely related to the concepts of Phi0-junctions and anomalous supercurrents.
Without delving into theoretical technicalities, I will attempt to provide a general overview of the field in this presentation, offering a historical perspective and highlighting results obtained from collaborations between my group in San Sebastián and Tero Heikkilä's group in Jyväskylä.
