We present single-crystal neutron scattering measurements of the spin-1/2 equilateral triangular-lattice antiferromagnet Ba3CoSb2O9. Besides confirming that the Co2+ magnetic moments lie in the ab plane for zero magnetic field and then...
Structural And Magnetic Properties Of Two Branches Of The Tripod-kagome-lattice Family A(2)r(3)sb(3)o(14) (a = Mg, Zn; R = Pr, Nd, Gd, Tb, Dy, Ho, Er, Yb)
We present a systematic study of the structural and magnetic properties of two branches of the rare-earth tripod-kagome-lattice (TKL) family A(2)R(3)Sb(3)O(14) (A= Mg, Zn; R= Pr, Nd, Gd, Tb, Dy, Ho, Er, Yb; here, we use abbreviation A-R, ...
We report infrared magnetospectroscopy studies on thin crystals of an emerging Dirac material ZrTe5 near the intrinsic limit. The observed structure of the Landau-level transitions and zero-field infrared absorption indicate a two...
For materials near the phase boundary between weak and strong topological insulators (TIs), their band topology depends on the band alignment, with the inverted (normal) band corresponding to the strong (weak) TI phase. Here, taking the...
We present the structural and magnetic properties of a new compound family, Mg2RE3Sb3O14 (RE = Gd, Dy, Er), with a hitherto unstudied frustrating lattice, the "tripod kagome" structure. Susceptibility (ac, dc) and specific heat exhibit...
