Metastable state of the photomagnetic Prussian blue analog
The thermodynamic properties of the photomagnetic Prussian blue analog K0.3Co[Fe(CN)6]0.77 · 3.6H2O, which exhibits a charge-transfer-induced spin transition (CTIST), are reported. According to the thermal history of the sample, different low-temperature states are obtained: a quenched high-spin state (Q), a low-spin state (LT) achieved through the decay of the Q state, and an intermediate stat...
متن کاملthe role of task-based techniques on the acquisition of english language structures by the intermediate efl students
this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...
15 صفحه اولMagnetic 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 کاملDecoding the fading of Prussian blue pigment
for art history issues. The task is complex however because of the highly heterogeneous character of a paint layer, which consists of a mixture of pigments and a binder on a support. All the components interact and infl uence the ageing process of the paint layer. The work described here is focused on understanding the discoloration over time of a particular pigment, Prussian blue, a synthetic ...
