YNiSn $_{2}$ : A candidate Dirac semimetal

G. S. Freitas, C. Kaufmann Ribeiro, F. B. Carneiro +16

We report the synthesis and physical properties of the new compound YNiSn $_{2}$ , which crystallizes in the orthorhombic \textit{Cmcm} structure. The material exhibits semimetallic be…

Magnetization of Bi $_{2}$ Sr $_{2}$ CaCu $_{2}$ O $_{8 + δ}$ micrometer thin ring and its depinning line

B. Semenenko, B. C. Camargo, A. Setzer +3

We demonstrate a geometrical effect on the depinning line (DL) of the flux line lattice of the Bi $_{2}$ Sr $_{2}$ CaCu $_{2}$ O $_{8 + δ}$ high-T $_{c}$ superconductor (HTSC) micrometer ring.…

Anomalous Hall Effect in Bismuth

Bruno Camargo, Piort Gierlowski, Andrei Alaferdov +4

We report the occurrence of ferromagnetic-like anomalous Hall effect (AHE) below $30$ mT in bismuth single and policrystals. The signatures of ferromagnetism in transport are not c…
