Single Molecule Magnets(SMM)
Posted: Mon Apr 16, 2018 3:47 pm
Can one simulate magnetization or hysteresis curves of SMM? These molecules are defined by a single giant spin(S=10), thus neglecting the coupling between electrons. Normal they have both transverse and longitudinal anisotropy. I tried to simulate Mn12Ac with curry but couldn't get any steps in magnetization. Here's my code:
Code: Select all
clear, clc, clf
Sys.S = 10;
Sys.D = 0.65*20836.6176;
Sys.C = -0.06*20836.6176*1e-3;
Exp.Temperature = 0.05 ;
Exp.Field = linspace(-3,3,500)*1e3;
mu_z = curry(Sys,Exp);
plot(Exp.Field/1e3, mu_z/max(mu_z));
