Here, we report the first successful exfoliation of two-dimensional\nTi3C2Tx MXene through selective etching of silicon from titanium\nsilicon carbide (Ti3SiC2) MAX. The successful etching and exfoliation of\nMXene is confirmed through the shifting of all (00l) peaks to lower angles\nalong with the increase in c-lattice parameter as determined by X-ray\ndiffraction technique to detail the material structure. The c-lattice parameter\nof multilayered MXene was found to be 19.34 AA which was increased to 26.22\n AA after delamination process indicating the successful intercalation of\nTMA+ ions within the MXene Sheets. The scanning electron microscopy (SEM)\nimages show the formation of 2D layered structure. The magnetic measurement of\nthe etched MXene sample was measured using superconducting quantum interference\ndevice (SQUID: Quantum Design). The magnetization vs magnetic (M-H) curves\nclearly indicate the ferromagnetic-dominant hysteresis loops at low-temperature\nas well as at room-temperature along with the presence of small diamagnetic\nphase due to the presence of silicon carbide (SiC) present in MXene structure.\nThe presence of SiC phase is confirmed through XRD and Raman spectra that show\nthe sharp peaks and vibrational modes of SiC within 2D MXene structure. The\npresent work shows the co-existence of ferromagnetic and diamagnetic phases\nmaking it suitable 2D material for future spintronics devices.\n
