Journal ArticleDOI
Perovskite metal formate framework of [NH2-CH(+)-NH2]Mn(HCOO)3]: phase transition, magnetic, dielectric, and phonon properties.
TL;DR: Temperature-dependent studies show that the phase transition in FMDMn is associated with ordering of the FMD(+) cations, and detailed analysis shows, however, that these cations still exhibit some reorientational motions down to about 200 K.
Journal ArticleDOI
Phase Transitions and Coexistence of Magnetic and Electric Orders in the Methylhydrazinium Metal Formate Frameworks
Mirosław Mączka,Anna Gągor,Maciej Ptak,Waldeci Paraguassu,Tercio Almeida da Silva,Adam Sieradzki,Adam Pikul +6 more
TL;DR: In this article, the synthesis of four perovskite-type metal formate frameworks, [CH3NH2NH2][M(HCOO)3] (MHyM) with M = Mn, Mg, Fe, and Zn, was reported.
Journal ArticleDOI
Methylhydrazinium Lead Bromide: Noncentrosymmetric Three-Dimensional Perovskite with Exceptionally Large Framework Distortion and Green Photoluminescence
TL;DR: The 3D lead halide perovskites have emerged as a promising class of coordination polymers for solar cells, photodetectors, and light-emitting devices.
Journal ArticleDOI
Experimental and theoretical studies of structural phase transition in a novel polar perovskite-like [C2H5NH3][Na0.5Fe0.5(HCOO)3] formate.
Maciej Ptak,Mirosław Mączka,Anna Gągor,Adam Sieradzki,Alessandro Stroppa,Domenico Di Sante,J. M. Perez-Mato,Lucyna Macalik +7 more
TL;DR: The synthesis, single crystal X-ray diffraction, and thermal, dielectric, Raman and infrared studies of a novel heterometallic formate (EtANaFe) indicate that the driving force of the phase transition is ordering of EtA(+) cations, however, this ordering is accompanied by significant distortion of the metal formate framework.
Journal ArticleDOI
Three-Dimensional Perovskite Methylhydrazinium Lead Chloride with Two Polar Phases and Unusual Second-Harmonic Generation Bistability above Room Temperature
Miroslaw Maczka,Anna Gagor,Jan K. Zarȩba,Dagmara Stefańska,Marek Drozd,Sergejus Balciunas,Mantas Šimėnas,Juras Banys,Adam Sieradzki +8 more
TL;DR: In this paper, the polar structure of lead halide perovskites has been exploited for the formation of noncentrosymmetric three-dimensional (3D) lead halides.
