SOTs emerge from the spin-charge locking established by the break of spacial inversion symmetry. This break can occur at the interface in a multilayer heterostructure or within the unit cell of a ferromagnet. In this talk I will discuss my studies on SOTs [1] and on their reciprocal effect, magnonic charge pumping [2], in inversion asymmetric ferromagnets. I will also discuss some new prospects where the break of inversion symmetry acts as a linking element that couples two states of matter traditionally considered incompatible, ferromagnetism and BCS superconductivity [3]. In the second part of the talk, I will focus on our efforts to move our spintronics studies towards ultra-fast timescales particularly focusing on the picosecond readout of an antiferromagnetic state via THz emission spectroscopy.
