Ubiquitous Order-Disorder Transition in the Mn Antisite Sublattice of the (MnBiTe)(BiTe) Magnetic Topological Insulators.

Magnetic topological insulators (TIs) herald a wealth of applications in spin-based technologies, relying on the novel quantum phenomena provided by their topological properties. Particularly promising is the (MnBiTe)(BiTe) layered family of established intrinsic magnetic TIs that can flexibly realize various magnetic orders and topological states. High tunability of this material platform is enabled by manganese-pnictogen intermixing, whose amounts and distribution patterns are controlled by synthetic conditions.

Synthesis and Characterization of Oxide Chloride SrVOCl, a Layered = 1 Compound.

The mixed-anion compound with composition SrVOCl has been synthesized for the first time, using the conventional high-temperature solid-state synthesis technique in a closed silica ampule under inert conditions. This compound belongs to the known Sr OCl ( = Sc, Mn, Fe, Co, Ni) family, but with = V. All homologues within this family can be described with the tetragonal space group 4/ (No.

Intermixing-Driven Surface and Bulk Ferromagnetism in the Quantum Anomalous Hall Candidate MnBi Te.

The recent realizations of the quantum anomalous Hall effect (QAHE) in MnBi Te and MnBi Te benchmark the (MnBi Te )(Bi Te ) family as a promising hotbed for further QAHE improvements. The family owes its potential to its ferromagnetically (FM) ordered MnBi Te septuple layers (SLs). However, the QAHE realization is complicated in MnBi Te and MnBi Te due to the substantial antiferromagnetic (AFM) coupling between the SLs.
