Altermagnetism (AM) is an emerging type of magnetism, combining advantages of both antiferromagnetism (AFM) and ferromagnetism (FM), with no net magnetization and spin-splitting Fermi surfaces. It is ideal material for spintronic applications. In our work, we studied the inverse altermagnetic spin-splitting effect (IASSE) in epitaxial RuO2 film capped by ferromagnetic insulator YIG layer. By injecting a spin current from YIG into RuO2, we observed a significant anisotropic spin to charge conversion with spin index parallel or perpendicular to the Néel vector directions, revealing the inverse altermagnetic spin-splitting effect (IASSE) in RuO2. Furthermore, we verify the ordering of the Néel vector along the [001] direction from magnetization measurements. Our study provides critical insights in the understanding of altermagnetism.
