  We investigate anomalous spin and orbital Hall phenomena in antiferromagnetic
(AF) materials via orbital pumping experiments. Conducting spin and orbital
pumping experiments on YIG/Pt/Ir20Mn80 heterostructures, we unexpectedly
observe strong spin and orbital anomalous signals in an out-of-plane
configuration. We report a sevenfold increase in the signal of the anomalous
inverse orbital Hall effect (AIOHE) compared to conventional effects. Our study
suggests expanding the Orbital Hall angle ({\theta}_OH) to a rank 3 tensor,
akin to the Spin Hall angle ({\theta}_SH), to explain AIOHE. This work pioneers
converting spin-orbital currents into charge current, advancing the
spin-orbitronics domain in AF materials.
