Single Molecule Magnets(SMM)

[jiten.phy]

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));

Unfortunately, this is currently not possible.
