Thickness-dependent ferromagnetic metal to paramagnetic insulator transition in La${}_{0.6}$Sr${}_{0.4}$MnO${}_3$ thin films studied by x-ray magnetic circular dichroism

Metallic transition-metal oxides undergo a metal-to-insulator transition (MIT) as the film thickness decreases across a ritical thickness of several monolayers (MLs), but its drivi…
