  Spin Hall effects interconvert spin- and charge currents due to spin-orbit
interaction, which enables convenient electrical generation and detection of
diffusive spin currents and even collective spin excitations in magnetic
solids. Here, we review recent experimental efforts exploring efficient spin
Hall detector materials as well as new approaches to drive collective
magnetization dynamics and to manipulate spin textures by spin Hall effects.
These studies are also expected to impact practical spintronics applications
beyond their significance in fundamental research.
