Strain induced stabilization of a static Jahn-Teller distortion in the O $^{*}$ -phase of La $_{7/8}$ Sr $_{1/8}$ MnO $_{3}$

Michael Dettbarn, Volodymyr B. Zabolotnyy, Abdul V. Tcakaev +5

At room temperature, bulk La $_{7/8}$ Sr $_{1/8}$ MnO $_{3}$ is in the dynamic Jahn--Teller O $^{*}$ phase, but undergoes a transition to a static, magnetically ordered Jahn--Teller phase at…

Incipient antiferromagnetism in the Eu-doped topological insulator Bi $_{2}$ Te $_{3}$

Abdul Tcakaev, Volodymyr B. Zabolotnyy, Celso I. Fornari +14

Rare earth ions typically exhibit larger magnetic moments than transition metal ions and thus promise the opening of a wider exchange gap in the Dirac surface states of topological…

Ubiquitous impact of localised impurity states on the exchange coupling mechanism in magnetic topological insulators

Thiago R. F. Peixoto, Hendrik Bentmann, Philipp Rüßmann +27

Since the discovery of the quantum anomalous Hall effect in the magnetically doped topological insulators (MTI) Cr:(Bi,Sb) $_{2}$ Te $_{3}$ and V:(Bi,Sb) $_{2}$ Te $_{3}$ , the search for the exc…
