J is used, actually. As ias just the total value of the spin.

Hi Vitbka,

Greetings,

In your script, you have used the “spin” model, where parameter J is not used.

If I hadn’t made a mistake, maybe you should try S instead? Please look at the picture.

Kind regards,

Tamama

What do you call Jxy and what is Jyx?
