Here, we report on the interlayer DMI between two orthogonally magnetized ferromagnetic layers (Co-Fe-B/Co) mediated by a Pt layer and confirm the chiral nature of the observed effective field of up to 37 Oe through asymmetric hysteresis loops under an in-plane field. We highlight the importance of growth-induced in-plane symmetry breaking, resulting in a sizable interlayer DMI and a universal characteristic vector through wedge deposition of the samples. We further perform deterministic current-driven magnetization switching in the perpendicularly magnetized Co layer utilizing solely the effective field from the interlayer DMI. These results demonstrate the interlayer DMI's potential to facilitate deterministic field-free switching in spin-memory applications.SPIN-ORBIT TORQUE; PERPENDICULAR MAGNETIC-ANISOTROPY; SKYRMIONS; DRIVEN; Physics - Materials Science; Physics - Materials Sciencejournal article10.1103/PhysRevApplied.18.0340462-s2.0-85139313429WOS:000865450000004https://api.elsevier.com/content/abstract/scopus_id/85139313429
