摘要：
The magnetic properties of molecular nanomagnets Mn (12)-Ac (acetate) through Ising model are studied by using the Monte Carlo simulations. The effect of exchange interactions are studied in the molecular nanomagnets Mn (12)-Ac. The reduced exchange interaction versus the reduced exchange interaction and external magnetic field in Mn (12)-Ac shell-core structure is given. The reduced exchange interaction in shell-core versus the crystal field is studied. The effect of external magnetic in the crystal field is established. The blocking temperature is given for different values of crystal field and for temperature T = 1.0 K. The total magnetization versus crystal field and external magnetic field is given for different temperatures. The magnetic coercive field is given for different values of crystal field.
