Orbital angular momentum provides an alternative channel for current-induced magnetization switching beyond conventional spin–orbit coupling. While orbital Hall effects have been observed in several nonmagnetic materials, their manifestation in symmetry-compensated magnetic systems remains unexplored. Here, we report experimental evidence for a magnetic orbital Hall effect in RuO₂. In RuO₂(101)/Pt/Co heterostructures, we observe a pronounced unconventional torque characterized by a large out-of-plane component, strong crystalline anisotropy, and deterministic field-free switching of a perpendicular ferromagnet over a wide range of RuO₂ thicknesses. The torque exhibits a non-monotonic dependence on Pt thickness, reaching a maximum at 1.5 nm, and displays a long-range RuO₂ thickness (t_(RuO₂)) dependence that saturates for t_(RuO₂)>100 nm. These features cannot be reconciled with conventional spin-current mechanisms. Rather, they indicate a magnetic orbital Hall effect in RuO₂ that could originate from exchange-induced momentum-dependent band splitting and its interplay with spin–orbit and crystal-field coupling, with the generated orbital current converted into torque in Pt. Our findings establish altermagnets as intrinsic sources of orbital currents and extend orbitronics to symmetry-compensated magnetic systems.
