However, its potential in the emerging field of flexible spintronics remains largely unexplored. Here, we demonstrate a flexible and robust OT device based on a mica/SrRuO3(SRO)/CoPt heterostructure. We measure a large torque efficiency of -0.31, which originates from the significant orbital Hall effect in the SRO layer. Leveraging the low thermal conductivity of the mica substrate, a thermally-assisted switching mechanism is activated, enabling an ultralow threshold current density of 9.2x109 A/m2.
