Unlocking High Coercivity at Room Temperature in Phase Modified MoS ₂

2D materials showing room-temperature magnetism and high coercivity are highly attractive for combining magnetism with semiconducting functionality in spintronic devices. In this work, the magnetic properties of the 1T phase of MoS₂ have been studied at room temperature. We observe ferromagnetism with a coercivity of ∼0.3 T and a maximum saturation magnetization of 0.26 emu g^-1 at room temperature. This is the highest among coercivities reported so far in 2D magnets at room temperature. MoS₂ nanosheets are prepared using a single-step hydrothermal synthesis with a relative 1T-phase reaching up to 77%. Structural analysis reveals lattice expansion, reflected by an increased interplanar spacing, which correlates directly with both the relative 1T phase fraction and enhanced coercivity. Our findings demonstrate a direct structural route to engineer coercivity through phase and strain control in MoS₂, offering a scalable platform for phase-engineered magnetism in layered materials.
