Further in situ magnetization measurements were carried out for both as-received and cold rolled (ε¼0.916) materials. For each condition, two samples were cut according to the protocol described in item (ii). The first sample was obtained by means of conventional cutting (using low-speed diamond saw). However, the second one was deeply etched in aqua
regia solution for 60 s after cut. These four samples were submitted to magnetization measurements taken in the presence of a fixed external magnetic field (H//RD), in the temperature range 25–1000 °C, for a heating rate of 3 °C/min. The external magnetic field was 90 Oe and 115 Oe for the asreceived and cold rolled (ε¼0.916) samples, respectively. These magnetic fields promote a magnetization (M) equal to 10% of Ms in each correspondent sample
