Re: Fitting of magnetic susceptibility data

I want to resume again the case, two coupling constant J1 and J2 and one g to fit a Chi vs T curve. the code is clear all; close all; cm=2.99793e4; % Conversion constant from cm-1 to MHz (~ 100*clight/1e6) path = 'C:\Users\AlDamen\Desktop\easyspin-5.0.22\Fitting'; cd(path); format long; [T,chi] = te...

Re: Fitting of magnetic susceptibility data

I carried out the following code based on your input with a moderate modification. The code is for tetrameric manganese with J1 for MnIII-MnIII J2 for MnII-MnIII 0 for MnII-MnII 2 for g and external data the code is : clear all; close all; cm=2.99793e4; % Conversion constant from cm-1 to MHz (~ 100*...

Magnetic Exchange and Magnetization, J, g, D

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 experimen...

Extract ZFS (D and E)

Dears, 1- I want to ask about an input, as I have a little experience in Matlab, the input mainly is to get D and E (ZFS) constants as well as J and g for a system of The figure can be found in the following journal : http://pubs.acs.org/doi/abs/10.1021/ic201683p which is a dicubane of Mn2IIIMn2IILn...
