We have investigated the critical current density (Jc) and the flux pinning behavior in Zr0.96V0.04B2superconductor with an AlB2structure. V substitutions in Zr sites of non-superconducting ZrB2system lead to superconductivity, and the 4% V-substitut

ZrB2is a nonsuperconducting Pauli paramagnetic crystallizing in the AlB2structure. V substitution for Zr in Zr1-xVxB2(0.01 ≤ x ≤ 0.1) at the few percentage level induces superconductivity with critical temperature reaching a maximum of 8.7 K for

Autor: MacHado, AJS, Costa, AMS, Nunes, CA, Dos Santos, CAM, Grant, T, Fisk, Z

Publikováno v: MacHado, AJS; Costa, AMS; Nunes, CA; Dos Santos, CAM; Grant, T; & Fisk, Z. (2011). Superconductivity in Mo5SiB2. Solid State Communications, 151(20), 1455-1458. doi: 10.1016/j.ssc.2011.07.005. UC Irvine: Retrieved from: http://www.escholarship.org/uc/item/8pk4g90t

In the MoSi binary system, Mo5Si3crystallizes in the W5Si3(T1phase) structure type. However, when boron replaces silicon in this compound, a structural transition occurs from the W5Si3prototype structure to the Cr5B3prototype structure (T2phase) at t

In this work the Ti2InN phase is investigated by X-ray diffraction, magnetic and resistivity measurements. X-ray powder patterns suggest that all peaks can be indexed with the hexagonal phase of Cr2AlC prototype. Electrical resistance as a function o
