Thank you Stefan, with the latest version it works now. Thank you very much!

Hello guys, could someone tell me why the magnetic field showed on the picture (stopped at 5000mT) is not consistent with the field range I typed in the code(FieldRange= [0 5e6])? Thank you very much! The codes are as below: mySystem = struct('S',1/2,'g',1.067,'D',-2044); Ori = [0 0]; FieldRange = [...

Hello everyone! If one ion has two groups of spectrums which including two goups of different zero field splitting (ZFS) parameters, could someone tell me how to input spin Hamiltonian parameters in Easyspin to get ZFS spectrum? Thank you very much!

Regards,

Add: Hi Stefan, do you remember i asked help from you about the right picture in attachment? You said it seems ok for you. But compared with Figure 2 in this paper https://journals.aps.org/pr/pdf/10.1103/PhysRev.148.211 It seems in my plot , states|-5/2> and |3/2> have a mixture. But in this paper, ...

Thank you, it worked very well. I would like to know if it is possible to get the spin Hamiltonian matrix (or energy of different energy levels) denoted by the zero field splitting parameters( D, a, F...) when applied with a magnetic field along a specific direction.

Thank you Stefan. Could you tell me how to diagonalize it? By the way, how can i get the matrix of spin Hamiltonian? Thank you again.

Hello, I would like to ask how to describe the spin system in ZFS when there exists the admixture of two spin states. Thanks.

Hello, Stefan, thanks for your kindly reply. Could you tell me except the examples inside the Easyspin is there any books I can reference so that I can find more details about this software. Thank you!

Thank you,Stefan. Yes, you are right. The left picture is a S=3/2 system with an I=7/2 nucleus. The script is as below:

Sys.S=3/2;
Sys.g=1.991;
Sys.D=-4803.6;
Sys.A=-220.615;
Sys.B=-222.890;
Sys.Nucs='51V';
Ori=[0 0];
FieldRange = [0 1000];
levelsplot(Sys,Ori,FieldRange)

Hello everyone, I am trying to using EasySpin to simulate the zero field splitting, but it seems that the upper part of the left picture (red square) is not so clear and it's not splitting from the same point (green square). Another problem is when I try to select one splitting line it's not followi...
