Herein, we report a magnetoplasmonic nanofluid comprising core–shell MnFe2O4@Fe3O4 nanocubes and gold nanorods that exhibits significantly enhanced magnetic hyperthermia performance under kHz-range alternating magnetic fields. A marked increase in heating efficiency, up to 50% higher specific absorption rate (SAR) compared to the ferrite-only control samples, was observed when the plasmon resonance of the Au nanorods aligned with near-infrared optical transitions of the ferrite nanocubes. This enhancement is attributed to the polariton-like hybridization phenomenon in the near field. Such findings open potential avenues for engineering multifunctional nanomaterials for targeted cancer therapy and theragnostic applications.2026http://zaguan.unizar.es/record/16850510.1021/acsanm.5c05187http://zaguan.unizar.es/record/168505oai:zaguan.unizar.es:168505info:eu-repo/grantAgreement/ES/MICINN-AEI/PRTR-C17.I1info:eu-repo/grantAgreement/ES/MICINN/CEX2021-001214-Sinfo:eu-repo/grantAgreement/EUR/MICIU/PID2023-150767OB-I00ACS APPLIED NANO MATERIALS 9, 5 (2026), 2442-2452by-nc-ndhttps://creativecommons.org/licenses/by-nc-nd/4.0/deed.esinfo:eu-repo/semantics/openAccess
