Quantum Magnetism is a field that studies unusual and novel states of matter, such as quantum magnets. These magnetic materials retain large quantum fluctuations even at T=0 K, arising from factors such as low dimensionality, geometrical frustration, small spin magnitudes, and sizeable spin-orbit coupling effects. The quantum spin liquid (QSL) state, predicted by P. W. Anderson, is relevant to future applications in quantum computing and secure quantum information transmission. However, there are challenges in this field, such as the proposal of the "floating phase" for high spin value MG chains. The main objective is to study different varieties of quantum magnets in different dimensions like 1D, 2D, and 3D. The proposed experiments include single-crystal growth, X-ray diffraction, magnetization, heat capacity, solid-state NMR, muon spin rotation at extreme conditions, and inelastic scattering experiments. First-principles calculations will be carried out using density functional theory + Hubbard U (DFT+U) and DFT+dynamical mean field theory (DMFT) based approaches. The project aims to explore new phases of matter, such as the floating phase, the ground state of the 2D square lattice with Jeff = ½ moments, and the existence of the quantum spin liquid phase in large spin values with 3D frustrated cubic systems.
