I am trying to fit the formula in the first picture to my magnetic susceptibility as a function of temperature data, but, I dont know how to use the summation in the NLfitting function in Origin. Can anyone help?

I also have a question on calling Langevin function into a susceptibility formula as shown in image 2, but, I dont know how to do that either. Please help.

Many thanks in advance.
Kind regards
