Figure 2
Geometric sketches illustrating the condition for the derivation of ρm,μ. Shown are three spiral nodes each of two adjacent spiral branches, forming a chevron-like pattern 〉〈 at the centre of each unit cell within a twin domain (Fig. 8). The left-hand side illustrates the general, non-ideal, case, while the right-hand side illustrates the special, ideal, case, in which the vectors v∥ and v⊥ are perpendicular, thereby fixing the ideal value of ρm,μ as a function of the parameters m and μ. |
