Abstract
This thesis presents a study of Kagome material using Nuclear Magnetic Resonance (NMR) and Nuclear Quadrupole Resonance (NQR) spectroscopy. Kagome materials are a class of quantum materials known for their unique 2D lattice structure, making them intriguing candidates for investigating exotic phases of matter. The properties of the 2nd NQR transition of 121Sb of CsV3Sb5 will be studied at room temperatures, in Charge Density Wave Transition state and also by varying the temperatures to study how the doping density change the CDW Temperature. The samples under investigation will be undoped, 4% Cr, 4% Te and 10% Cr doped samples. Measurements like spectra analysis, T1 and T2 measurements will be carried out to notice the effect of doping in the spectral width, frequency shifts, density of states at Fermi level and shift in the transition temperatures. The outcome contributes to the understanding of the kagome lattice, NMR/NQR spectroscopy and the effect of doping on Charge Density Wave Transition.
