Hi all,
I am trying to define a nanoparticle which is paramagnetic inside of a magnetic region. I have attached an image below for clarification.
Thus far, I have set the magnetic saturation to 0. However, I also need to set exchange energy in this area to 0 for the simulation to run as intended.
As I am using Mumax3 as a calculator, the option of defining my exchange stiffness with a discretised field object is not available, and as my nanoparticle is circular I cannot define the exchange stiffness using a region either.
Does anyone have any ideas on how to get around this issue?
I have attached a notebook with my code in it, with the discretised field solution which didn't work with Mumax - any help or ideas is duly appreciated! (I am not entirely familiar with the etiquette of asking questions using GitHub either - please excuse any mistakes I have made.)
