Surface and electronic structure of SmB through Scanning Tunneling Microscopy
S. Roessler, Lin Jiao, D. -J. Kim +6
SmB, a so called Kondo insulator, is recently discussed as a candidate material for a strong topological insulator. We present detailed atomically resolved topographic informat…
Jahn-Teller distortion driven magnetic polarons in magnetite
H. Y. Huang, Z. Y. Chen, R. -P. Wang +11
The first known magnetic mineral, magnetite (FeO), has unusual properties which have fascinated mankind for centuries; it undergoes the Verwey transition at $\s…
Mn3TeO6 - A New Multiferroic Material with Two Magnetic Substructures
L. Zhao, Z. Hu, C. Y. Kuo +4
From magnetic susceptibility, dielectric permittivity, electric polarization and specific heat measurements, we discover spin-induced ferroelectricity and magnetoelectric coupling…
Crossover from a heavy fermion to intermediate valence state in noncentrosymmetric Yb2Ni12(P,As)7
W. B. Jiang, L. Yang, C. Y. Guo +14
We report measurements of the physical properties and electronic structure of the hexagonal compounds Yb2Ni12Pn7 (Pn = P, As) by measuring the electrical resistivity, magnetization…
CeRuSn: a strongly correlated material with nontrivial topology
M. Sundermann, F. Strigari, T. Willers +14
Topological insulators form a novel state of matter that provides new opportunities to create unique quantum phenomena. While the materials used so far are based on semiconductors,…
Protective capping of topological surface states of intrinsically insulating BiTe
Katharina Höfer, Christoph Becker, Steffen Wirth +1
We have identified epitaxially grown elemental Te as a capping material that is suited to protect the topological surface states of intrinsically insulating BiTe. By using…
