Magnetic Exchange and Magnetization, J, g, D

[aldamen]

Dears,

1- I want to know the way to make the following:
- A fitting of the magnetic susceptibility of a tetramer of manganese with two J,
Mn(III)-Mn(III) .... J1
Mn(II)-Mn(III) ... J2
Mn(II)-Mn(II) ... 0
there is one g for all the component and
one zJ

I want to fit the J's, zJ and g for an experimental exp.dat (T, CHI*T)

then I want to obtain the D for the system from the magnetization and susceptibility

to have more information , the system is here, the figure can be found in the following journal : http://pubs.acs.org/doi/abs/10.1021/ic201683p , which is a dicubane of Mn2IIIMn2IILnIII2 (four J and four g and D or E for all components)

I appreciate your help

This forum is about helping each other with problems regarding EasySpin simulations and not for actually doing the work of putting a simulation script together. That's why nobody has responded to your request. If you have specific problems with your simulation, then I am sure people will be happy to have a look and help out!
