Magnetic phase transitions in pure zigzag graphone nanoribbons

• We study pure graphone nanoribbons using MC calculations and mean field theory.
• We show the effects of the nanoribbon width on thermodynamic quantities.
• We study magnetic properties of GONR in presence of external magnetic field.
• We describe the influence of the system's parameters on the hysteresis curves.
• This work offer promise for use of GONR in high-energy-storage-capacitor applications.

Magnetic properties and hysteresis loops of pure graphone nanoribbons (GONR) are studied using both Monte Carlo calculations and mean field theory. This study is relevant for understanding the magnetic behavior of pure GONR that exhibits magnetism due to the localized electrons on the carbon atoms without hydrogens. Magnetization and its corresponding susceptibility are given for various ribbon widths 3≤Nz≤1003≤Nz≤100 and external magnetic field 0
