| Research Abstract |
Novel 1-D chiral cyanide-bridged ferromagnets, PPh_4[Ni(L)_2][Fe(CN)_6] have been prepared using chiral co-ligands (L). Two-step magnetic ordering was observed at 3.0 and 2.5 K, which was supported by linear and nonlinear ac magnetic responses, magnetic specific heat and μSR. These multiple results corroborated that the magnetic structure changed among the two-dimensional Ising-type paramagnetic phase above 3.0 K, the two-dimensional Ising ordered phase between 3.0 K and 2.5 K, and the three-dimensional magnetic ordered phase involving some chiral spin structures below 2.5 K. The trial of chirality transfer from the structure to the spin structure was succeeded in the one-dimensional molecular-based magnets incorporating chiral co-ligand and single-ion anisotropy.
