The interplay of non-Hermitian (NH) spin dynamics in coupled ferromagnetic (FM) systems has unveiled intriguing phenomena, notably the manifestation of FM-antiferromagnetic (AFM) phase transitions at exceptional points (EPs). Extending beyond traditional FM media, ferrimagnetic (FiM) media combine the advantages of AFM and FM systems, displaying distinct attributes especially at the angular momentum composition (AMC) point, xAMC.

Redox gating, a novel approach distinct from conventional electrolyte gating, combines reversible redox functionalities with common ionic electrolyte moieties to engineer charge transport, enabling power-efficient electronic phase control. In our study, we achieve a colossal sheet carrier density modulation beyond 1016 cm−2, sustainable over thousands of cycles, all within the sub-volt regime for functional oxide thin films.
