Publikováno v: Small 19, 2303176 (2023)

The magnetic anisotropy of low-dimensional Mott systems exhibits unexpected magnetotransport behavior useful for spin-based quantum electronics. Yet, the anisotropy of natural materials is inherently determined by the crystal structure, highly limiti

Room Temperature Ferroelectric Ferromagnet in 1D Tetrahedral Chain Network

Publikováno v: published in 2019

Ferroelectricity occurs in crystals with broken spatial inversion symmetry. In conventional perovskite oxides, concerted ionic displacements within a three-dimensional network of transition metal-oxygen polyhedra (MOx) manifest spontaneous polarizati
