High-energy heavy-ion collisions produce quark-gluon matter in strong rotation and immersed in short-lived, intense magnetic fields. These unique conditions enable studies of novel quantum chromodynamics phenomena, including chiral magnetic effects, global spin polarization, and spin alignment. Measurements in small systems also provide access to longitudinal polarization and local spin correlations. We review recent highlights from experiments at RHIC and the LHC, including the results on the chiral effects, intriguing hyperon global polarization, spin alignment, and local spin correlations.
