Thin and wiry : Ultrathin palladium and platinum nanowires with widths of 2.4±0.2 (Pd) and 2.3±0.2 nm (Pt) and lengths of over 30 nm are synthesized by a modified phase‐transfer method (see picture). Both nanowires show ferromagnetic properties and unusual shifts in their hysteresis loops at low temperature. ODA=octadecylamine, DTAB= n ‐dodecyltrimethylammonium bromide.
