Hello, I wish it would be helpful, but I do not understand what you mean when you say "on forward cyclic loading" and "controlled load instead". What I know is that the coercivity is calculated from the energy, varying an external parameter slowly and finding the global minimum for the variable to calculate, the best case is magnetism, where you have the energy and the external field is varied , finding the global minimum for magnetization using the Landau-lifshiftz-Gilbert LLG equation.
