Influence of Interdot Magnetostatic Interaction to Magnetization Reversal

GE Ze-ling1,ZHENG Yong-lin1,2(1.Department of Physics,Yangtze Normal University,Chongqing 408100,China;2.Institute of Electronics and Information Engineering,Chengdu University,Chengdu 610106,China)  
We established a physical model about the two-dimension magnetic granular array system,calculated the average magnetic moment by using energy minimum principle,and discussed the existence scope of ferromagnetic(FM),antiferromagnetic(AFM) and paramagnetic(PM),and the transition condition on square lattice particles from AFM to FM.The research shows that the critical temperature is Tc≈200K about nanometer magnetic partic system of low-thickness(v/a3≈0.05) for the magnetic order change.The system will occur state transition for AFM to FM when TTc and J2l-1=2γ2,and for FM to PM when TTc and J2l-1=2γ2T/Tc,and for AFM to PM when T=Tc and J2l-1≤2γ2.These characteristics may be very useful in sensor researching field at low temperature which needs large changes.
