Abstract Terahertz magneto-plasmonics plays a crucial role in platforms for isolation and sensing applications, operating at terahertz frequencies. In spite of recent efforts to enhance magneto-optic effects using metasurfaces, the mechanism optimizing these remains unclear regime. Here we investigate 100 nm-thick iron slot antennas with varying widths, ranging from 20 µm 300 nm. Interestingly, as width antenna decreases, this enhancement peaks around 1 µm, after which effect diminishes smaller widths. Based on effective medium theory, exhibit maximum Faraday rotation angle near epsilon-near-zero region. Although field enhancements become stronger sub-micron may decrease increasing dielectric constant due gap plasmon Our findings provide essential criteria designing ferromagnetic metasurfaces enhanced rotations
