Abstract (EN): We compute the valley/magnetic phase diagram of monolayers of transition-metal dichalcogenides in the hole-doped region where spin-orbit effects are particularly relevant. Taking into account the moderate to high local electron-electron interactions due to the presence of transition-metal atoms, we show that the system is unstable to an itinerant ferromagnetic phase where all charge carriers are spin and valley polarized. This phase shows an anomalous charge Hall and anomalous spin Hall response, and may thus be detected experimentally.
