“…Recently, compounds including mixed valence manganese oxides have been noted for the Colossal Magneto-Resistance (CMR) effect where many manganites with perovskite type structure have been mostly studied [1][2][3] and some compounds with layered perovskite type structures (A,Ln) 3 Mn 2 O 7 (A: alkaline earth) have been also reported, 4,5) and most of the reports on there compounds are described about the electric and the magnetic properties, [6][7][8][9][10][11] although a few reports are described about structure analysis. 12,13) BaLn 2 Mn 2 O 7 (Ln = Pr -Tb) compounds are one of a series of Ruddlesden-Popper type.…”

In order to clarify complicated phase behaviors and to obtain a unified explanation in such sequential phase transitions, formation of three kinds of tetragonal phases with a fundamental structure (I4/mmm) and the superstructures (P4 2 /mnm and Ccmm) for BaTb 2 Mn 2 O 7 are mainly discussed in this study. Single crystal of this compound was also grown by Floating Zone method. The crystal structure was analyzed by four circle X-ray method. As grown single crystal showed the tetragonal phase with a superstructure with the lattice parameters of a x a x c (a and c are lattice parameters of fundamental tetragonal cell). Thermal anomalies were observed at 440 K and 740 K from DSC curve. When this as-grown specimen was annealed in purified argon atmosphere at 1373K for several days and quenched to room temperature, this phase changed into the fundamental tetragonal phase. On the one hand, When same specimen was annealed in purified argon atmosphere at 573 K for several days and slowly cooled to room temperature, phase changed into the orthorhombic space group Ccmm. As grown crystals have P4 2 /mnm type tetragonal phase within the middle temperature, Ccmm type orthorhombic phase at room temperature and I4/mmm type tetragonal phase at high temperature.

Advanced materials and technologies for supercapacitors used in energy conversion and storage: a review

et al. 2020

Supercapacitors are increasingly used for energy conversion and storage systems in sustainable nanotechnologies. Graphite is a conventional electrode utilized in Li-ion-based batteries, yet its specific capacitance of 372 mA h g −1 is not adequate for supercapacitor applications. Interest in supercapacitors is due to their high-energy capacity, storage for a shorter period and longer lifetime. This review compares the following materials used to fabricate supercapacitors: spinel ferrites, e.g., MFe 2 O 4 , MMoO 4 and MCo 2 O 4 where M denotes a transition metal ion; perovskite oxides; transition metals sulfides; carbon materials; and conducting polymers. The application window of perovskite can be controlled by cations in sublattice sites. Cations increase the specific capacitance because cations possess large orbital valence electrons which grow the oxygen vacancies. Electrodes made of transition metal sulfides, e.g., ZnCo 2 S 4 , display a high specific capacitance of 1269 F g −1 , which is four times higher than those of transition metals oxides, e.g., Zn-Co ferrite, of 296 F g −1. This is explained by the low charge-transfer resistance and the high ion diffusion rate of transition metals sulfides. Composites made of magnetic oxides or transition metal sulfides with conducting polymers or carbon materials have the highest capacitance activity and cyclic stability. This is attributed to oxygen and sulfur active sites which foster electrolyte penetration during cycling, and, in turn, create new active sites.
