For a fixed applied field parallel to the RD, Fig. 6(a) and (b) show the temperature dependence of magnetization M(T) of
the as-received and 60% cold-rolled samples, respectively. In both figures (a) and (b), two curves of M(T) are displayed as well as their derivatives (see the insets). One of them is related to the sample cut in a conventional way (black line). The second one corresponds to the sample which was deeply etched after cutting (red line). From Fig. 6(a) and (b) there are no substantial differences between the two displayed M(T) curves.
