In this study, the nearest neighbor tight-binding model has been employed to calculate the density of states (DOS), electronic heat capacity (EHC), and Pauli magnetic susceptibility (PMS) of hydrogenated systems like graphone and graphane monolayers, bilayer graphane and bilayer graphane-graphone. Then, the results are compared. Monolayer graphone and bilayer graphane-graphone exhibit a high peak near the Fermi level. On the other hand graphane monolayer and bilayer graphane, have not states around the Fermi level. Also, the Schottky anomaly peaks in the EHC curves and the crossovers were observed in the PMS curves, which are divided into two regions of low and high temperature. With compation these systems, the Schottky anomaly in graphane monolayer and bilayer graphane equal in all temperatures. While the PMS of graphone monolayer and bilayer graphane-graphone were faster than other systems in reaching crossover. Theoretically, these phenomena are due to the proportional relation of the PMS and EHC with DOS.
