Article Synopsis
- The study focuses on how magnetic fields influence the formation of cobalt-aluminium layered double hydroxides, leading to the precipitation of tiny crystal structures.
- When a magnetic field is applied perpendicular to the surface, it results in the creation of dense and uniform films of these materials.
- The unique magnetic properties of the crystallites are attributed to a shift in the arrangement of cations, particularly favoring a honeycomb-like structure for cobalt ions.
The temperature behavior of the crystal structure as well as dielectric and magnetic properties of the perovskite bismuth chromate ceramics with the 10 mol % Cr-to-Sc substitution were studied and compared with those of the unmodified compound. Using a high-pressure synthesis, BiCrO and BiCrScO were obtained as metastable perovskite phases which are monoclinic 2/ with the √6 × √2 × √6 superstructure (where is the primitive perovskite unit-cell parameter) under ambient conditions. At room temperature, the unit cell volume of BiCrScO is ∼1.

- A thermal treatment after synthesis of the BiFe1-yScyO3 perovskite leads to the creation of new, stable structures that have unique magnetic characteristics.
- These new structures include both polar and antipolar forms, showcasing interesting properties not previously observed.
- The study suggests that this process of forming new polymorphs through annealing could occur in other materials as well.
