Magnetic Properties and Metastable States in Spin-Crossover Transition of Co-Fe Prussian Blue Analogues
The combination of spin transitions and magnetic ordering provides an interesting structure of phase transitions in Prussian blue analogues (PBAs). To understand the structure of stable and metastable states of Co-Fe PBA, it is necessary to clarify free energy as a function of magnetization and the fraction of the high-temperature component. Including the magnetic interaction between high-tempe...
متن کاملHydrogen storage in the dehydrated prussian blue analogues M3[Co(CN)6]2 (M = Mn, Fe, Co, Ni, Cu, Zn).
The porosity and hydrogen storage properties for the dehydrated Prussian blue analogues M3[Co(CN)6]2 (M = Mn, Fe, Co, Ni, Cu, Zn) are reported. Argon sorption isotherms measured at 87 K afford BET surface areas ranging from 560 m2/g for Ni3[Co(CN)6]2 to 870 m2/g for Mn3[Co(CN)6]2; the latter value is comparable to the highest surface area reported for any known zeolite. All six compounds show s...
متن کاملSynthesis and Structure of Prussian Blue Analogues
The Electrochemical Society Interface • Fall 2002 olecular magnetism is an evolving discipline relying on quantum chemistry, orbitals and Hamiltonians, organic and coordination chemistries, physics, and devices. Among the exciting molecule-based magnetic systems, Prussian blue analogues occupy a peculiar position. Prussian blue itself was described for the first time in 1704. Since this time, t...
متن کاملPrussian blue analogues of reduced dimensionality.
Mixed-valence polycyanides (Prussian Blue analogues) possess a rich palette of properties spanning from room-temperature ferromagnetism to zero thermal expansion, which can be tuned by chemical modifications or the application of external stimuli (temperature, pressure, light irradiation). While molecule-based materials can combine physical and chemical properties associated with molecular-scal...
متن کاملVacancy-driven magnetocaloric effect in Prussian blue analogues
We experimentally show that the magnetocaloric properties of molecule-based Prussian blue analogues can be adjusted by controlling during the synthesis the amount of intrinsic vacancies. For CsxNi II 4 [Cr (CN)6](8+x)/3, we find indeed that the ferromagnetic phase transition induces significantly large magnetic entropy changes, whose maxima shift from∼ 68 K to∼ 95 K by varying the number of [Cr...
