TL;DR
This study investigates how Ru doping affects magnetic ordering and structural distortion in BaFe2As2, revealing that magnetic and structural transitions remain coincident and compete with superconductivity as Ru concentration increases.
Contribution
It provides a systematic analysis of magnetic and structural transitions in Ru-doped BaFe2As2, highlighting their coexistence and competition with superconductivity.
Findings
Magnetic and structural transitions remain coincident with Ru doping.
Transitions are gradually suppressed and coexist with superconductivity.
Strong competition observed between superconductivity, magnetism, and structural distortion.
Abstract
We present a systematic investigation of the antiferromagnetic ordering and structural distortion for the series of Ba(Fe{1-x}Ru{x})2As2 compounds (0 <= x <= 0.246). Neutron and x-ray diffraction measurements demonstrate that, unlike for the electron-doped compounds, the structural and magnetic transitions remain coincident in temperature. Both the magnetic and structural transitions are gradually suppressed with increased Ru concentration and coexist with superconductivity. For samples that are superconducting, we find strong competition between superconductivity, the antiferromagnetic ordering, and the structural distortion.
