Superconductivity, antiferromagnetism, and neutron scattering

Entangling Superconductivity and Antiferromagnetism

Superconductivity and Antiferromagnetism

We study the structure of symmetric vortices in a Ginzburg–Landau model based on S. C. Zhang’s SO(5) theory of high temperature superconductivity and antiferromagnetism. We consider both a full Ginzburg–Landau theory (with Ginzburg–Landau scaling parameter κ < ∞) and a κ → ∞ limiting model. In all cases we find that the usual superconducting vortices (with normal phase in the central core regio...

Coexistence of Antiferromagnetism and Triplet Superconductivity

Antiferromagnetism and superconductivity in the half-Heusler semimetal HoPdBi

We observed the coexistence of superconductivity and antiferromagnetic order in the single-crystalline ternary pnictide HoPdBi, a plausible topological semimetal. The compound orders antiferromagnetically at TN = 1.9 K and exhibits superconductivity below Tc = 0.7 K, which was confirmed by magnetic, electrical transport and specific heat measurements. The specific heat shows anomalies correspon...

Structure, antiferromagnetism and superconductivity of the layered iron arsenide NaFeAs.

A new layered iron arsenide NaFeAs isostructural with the superconducting lithium analogue displays evidence for the coexistence of superconductivity and magnetic ordering.
