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 کاملDynamical Aspects of Photoinduced Magnetism and Spin-Crossover phenomena in Prussian Blue Analogs
We present dynamical properties of spin crossover compounds with photomagnetization, proposing a new model in which the spin-crossover phenomena and magnetic ordering are incorporated in a unified way. By using this model, the novel characteristics observed in Prussian blue analogs are qualitatively well reproduced. We investigate the time evolution of the magnetization and high spin fraction t...
متن کاملPrussian Blue Analogue Mesoframes for Enhanced Aqueous Sodium-ion Storage
Mesostructure engineering is a potential avenue towards the property control of coordination polymers in addition to the traditional structure design on an atomic/molecular scale. Mesoframes, as a class of mesostructures, have short diffusion pathways for guest species and thus can be an ideal platform for fast storage of guest ions. We report a synthesis of Prussian Blue analogue mesoframes by...
متن کاملEnforcing Multifunctionality: A Pressure-Induced Spin-Crossover Photomagnet.
Photomagnetic compounds are usually achieved by assembling preorganized individual molecules into rationally designed molecular architectures via the bottom-up approach. Here we show that a magnetic response to light can also be enforced in a nonphotomagnetic compound by applying mechanical stress. The nonphotomagnetic cyano-bridged Fe(II)-Nb(IV) coordination polymer {[Fe(II)(pyrazole)4]2[Nb(IV...
متن کاملPressure-induced spin crossover in ferropericlase: an alternative concept
Ferropericlase (Mg,Fe)O is the second most abundant mineral in the Earth’s lower mantle after (Mg,Fe)SiO3 perovskite. Its high-pressure and high-temperature properties are crucial for the determination of the Earth’s deep interior model. The hypothesis of a pressure-induced spin transition of Fe ions in geologically relevant materials was proposed more than 40 years ago [1], but the experimenta...
