Magnetic properties of B-site mixed of quantum spin liquid in the triangular ferromagnetic Sr₃CuSb₂O₉ system

It was reported in recent experimental studies that the stratified triangular system Sr₃CuSb₂O₉ presents a quantum spin liquid without a gap and this phase of matter is well researched. The exchange interactions between the magnetic atoms in the same plan and interplans are found by using the density functional theory. The obtained results are used as input Monte Carlo study with Metropolis algorithm adopting the Ising model to study the magnetic and thermodynamic properties of spin-1/2. Thermal magnetization, internal energy, the specific heat and magnetic hysteresis cycles were determined. The transition temperature and superparamagnetic behavior are found. The superparamagnetic, ferromagnet and paramagnet phases are found. These novel magnetic can potentially be used in nanoelectronic devices, magnetic sensors, and flexible magnets. (author)
