Incipient antiferromagnetism in the Eu-doped topological insulator BiTe
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…
Morphology Control in van der Waals Epitaxy of Bismuth Telluride Topological Insulators
Celso I. Fornari, Eduardo Abramof, Paulo H. O. Rappl +2
Bismuth telluride have regained significant attention as a prototype of topological insulator. Thin films of high quality have been investigated as a basic platform for novel spint…
Hybrid reflections from multiple x-ray scattering in epitaxial bismuth telluride topological insulator films
Sergio L. Morelhao, Stefan Kycia, Samuel Netzke +3
Epitaxial films of bismuth telluride topological insulators have received increasing attention due to potential applications in spintronic and quantum computation. One of the most…
Hypergiant spin polarons photogenerated in ferromagnetic europium chalcogenides
X. Gratens, Yunbo Ou, J. Moodera +2
We find that in the ferromagnetic semiconductor EuS, near its Curie temperature, a single band-edge photon generates a spin polaron (SP), whose magnetic moment approaches 20,000 Bo…
