WebbThe results showed that the shapes of hysteresis loop indicated that the pores were probably slit-shaped or formed by plate-like particles, which could be confirmed by the SEM examination. It was noted that the apparent density used for pore volume calculation presented a higher possibility of underestimation. WebbThe simulated magnetic characteristic calculates the initialisation (first magnetisation curve), starting from an unmagnetised state, followed by its saturated hysteresis loop. For the first simulations the following parameters are used: Msat = 76500 A/m, a = 7012 A/m, α = 0.01, c = 0.18 and k = 3942.
