Room temperature ferroelectricity in fluoroperovskite thin films
Autor: Ming Yang, Amit KC, A. C. Garcia-Castro, Pavel Borisov, E. Bousquet, David Lederman, Aldo H. Romero, Cheng Cen
Publikováno v: Scientific Reports, Vol 7, Iss 1, Pp 1-9 (2017)
Abstract The NaMnF3 fluoride-perovskite has been found, theoretically, to be ferroelectric under epitaxial strain becoming a promising alternative to conventional oxides for multiferroic applications. Nevertheless, this fluoroperovskite has not been

Anionic nickel and nitrogen effects in the chiral antiferromagnetic antiperovskite Mn3NiN
Autor: E. Triana-Ramírez, W. Ibarra-Hernandez, A. C. Garcia-Castro
Publikováno v: Physical Chemistry Chemical Physics. 25:14992-14999
Magnetic antiperovskites, holding chiral noncollinear antiferromagnetic ordering, have shown remarkable properties that cover from negative thermal expansion to anomalous Hall effect. Nevertheless, details on the electronic structure related to the o

Unveiling the mechanisms behind the ferroelectric response in the Sr(Nb,Ta)O2N oxynitrides
Autor: A. C. Garcia-Castro, Alessandra Romero, J. S. Gelves-Badillo
Publikováno v: Physical Chemistry Chemical Physics. 23:17142-17149
Oxynitride perovskites of the type ABO2N have attracted considerable attention thanks to their potential ferroelectric behavior and tunable bandgap energy, making them ideal candidates for photocatalysis processes. Therefore, in order to shed light o
