Low crystal symmetry of magnetic van der Waals materials naturally promotes spin-orbital complexityunachievable in common magnetic materials used for spin-orbit torque switching. Here, using first-principlesmethods, we demonstrate that an interplay of spin and orbital degrees of freedom has a profound impact onspin-orbit torques in the prototypical van der Waals ferromagnet Fe 3 GeTe 2 . While we show that bulk Fe 3 GeTe 2hosts strong “hidden” current-induced torques harvested by each of its layers, we uncover that their originalternates between the conventional spin flux torque and the so-called orbital torque as the magnetizationdirection is varied. A drastic difference in the behavior of the two types of torques results in a nontrivial evolutionof switching properties with doping. Our findings promote the design of nonequilibrium orbital properties as theguiding mechanism for crafting the properties of spin-orbit torques in layered van der Waals materials. |
