contents	Two-dimensional (2D) materials showing room-temperature magnetism and high coercivity are desired for combining magnetism with semiconducting properties useful for spintronics. In this work, the magnetic properties of the 1T phase of MoS$_2$ 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 at room temperature. This is the highest among coercivities reported so far in 2D magnets at room temperature. MoS$_2$ nanosheets are prepared using a single-step hydrothermal synthesis with a relative 1T-phase reaching up to 77%. We report a correlation between the structural and magnetic characteristics via interplanar distance and coercivity. The increase in interplanar distance is also accompanied by an increase in the 1T phase. Our results pave a useful way of controlling the coercivity and saturation magnetization in a 2D magnet with applications in spintronics and low-power quantum devices.
