Paper that uses FEMM

Good morning for all. 
I am writing my master degree thesis and I used FEMM
to calculate de magnetic flux B in a sensor. I am
needing a paper or a thesis that uses FEMM too because
I need to reference this paper in my thesis to
validade the calculated results. If some one can help
me...
I am sending a paper to ilustrate my application.

Thanks for your help.
