Discrimination between two memory channels by molecular alloying in a doubly bistable spin crossover material.

ABSTRACT: A multistable spin crossover (SCO) molecular alloy system [Fe_1-x M _x (nBu-im)₃(tren)](P_1-y As _y F₆)₂ (M = Zn^II, Ni^II; (nBu-im)₃(tren) = tris(n-butyl-imidazol(2-ethylamino))amine) has been synthesized and characterized. By controlling the composition of this isomorphous series, two cooperative thermally induced SCO events featuring distinct critical temperatures (T _c) and hysteresis widths (ΔT _c, memory) can be selected at will. The pristine derivative 100As (x = 0, y = 1) displays a strong cooperative two-step SCO and two reversible structural phase transitions (PTs). The low temperat
