                         model extended to include phenomenological contributions of 
                         second-order magnetic anisotropy and coercivity mechanism with

                         our computational modeling using samples having particles with 
                         different sizes and different angular distributions of the easy 
                         axis of magnetization. A simple numerical approach with minimum of

                         the samples. Reasonable simulation results are generated based on
