• produced by vaporization from a resistively heated iron wire (current 2.7 A, diameter 250 μm, purity 99.95%, Goodfellow, USA) in a H2/Ar (7/93 mol ratio) flow of 480 cm3·min−1 inside an aluminium oxide (Al2O3) tube (inner diameter 16 mm). Particles formed and grew through vapor nucleation–condensation and

Consequently, by the creation of triangular patches in a 6√3×6√3R30° superstructure, the polar-stabilization requirements are met.
