Magnetic properties of dendrimer structures with different coordination numbers: A Monte Carlo study

•The dendrimer structure is investigated using Monte Carlo simulations.•The transition temperatures are obtained for different coordination numbers and generations.•The magnetic hysteresis cycle has been established.•The dendrimer structure exhibit the superparamagnetic behavior.

We investigate the magnetic properties of Cayley trees of large molecules with dendrimer structure using Monte Carlo simulations. The thermal magnetization and magnetic susceptibility of a dendrimer structure are given with different coordination numbers, Z=3, 4, 5 and different generations g=3 and 2. The variation of magnetizations with the exchange interactions and crystal fields have been given of this system. The magnetic hysteresis cycles have been established.
