value of the crystal field parameter D

[kstasz84]

Dear Sir,

My name is Krzysztof Staszkiewicz, I am a MSc student in the Department of Physics of University of Warsaw graduating this year.

I am writing to you in the following case:

I used “Easyspin” program to fit the angular dependence of the resonance field for layered system. Unfortunately, the value of the crystal field parameter D is large and the function cannot be fitted.

Could you advise me how to apply “Easyspin” in such case?
Is there any solution which you recommend?

I am looking forward to your reply.

Yours sincerely,

[Matt Krzyaniak]

Could you perhaps provide us an example of matlab script you're using that's not working.
