What is Effect of a low magnetic field on crystallinity and magnetic susceptibility of molecular magnet {NBu4[FeCr(ox)3]}x (NBu4+=tetra( n-butyl) ammonium ion; ox2−=oxalate ion) about?

Molecular magnet {NBu 4 [Fe Cr(ox) 3 ]} x (NBu 4 + 1⁄4 tetra(n-buty1) ammonium ion; ox 2À 1⁄4 oxalate ion) was synthesized under an applied low magnetic field of 0.3 T in comparison to that synthesized without a field. Their crystallinities, morphologies and magnetic properties were characterized by using the X-ray diffractionmeter, the transmission electron microscope, and a superconducting quantum interference device. It is found that the average size of particles synthesized under the applied field appears larger than that synthesized without a field. Moreover, its crystallinity, morphology and magnetic susceptibility have also been improved. However, its chemical structure and ferromagnetic phase transition temperature T c do not change. Possible reasons to explain this effect are also discussed.
