Temperature\u2010dependent magneto\u2010optical Kerr effect measurements confirm thermally activated switching of the  cluster octupole moment near the N\u00e9el temperature, while preserving predominantly in\u2010plane magnetic order. In  heterostructures, however, pronounced room\u2010temperature ferromagnetic signatures are observed, including enhanced Kerr rotation and out\u2010of\u2010plane magnetization. Systematic magnetometry studies reveal the formation of an intermixed  interfacial phase upon annealing. Ultrafast transport measurements using a sample with optimized interfaces show that optical excitation of  generates predominantly anomalous Nernst currents, with no detectable evidence of efficient spin\u2013current injection into Pt. In contrast,  exhibits a significant inverse spin Hall conversion when driven by spin currents injected from , reaching approximately  of the efficiency of Pt\u2010based reference structures. The conversion efficiency is found to be independent of the relative orientation between ferromagnetic magnetization and antiferromagnetic octupole moment.
