Spin currents in systems without net magnetization are critical for developing next-generation spin-orbit-torque and spintronic memory technologies. While altermagnets should provide such spin currents, they can also originate from pure interfacial effects. The authors take angle-dependent magnetotransport measurements of epitaxial ruthenium dioxide--permalloy heterostructures, revealing that strong interfacial effects dominate over potential altermagnetic contributions. This insight into interfacial spin-transport mechanisms is essential for advancing altermagnet-based spintronic applications.
