Uniaxial pressure effect on the magnetic ordered moment and transition temperatures in BaFe${}_{2-x}{T}_x$As${}_2$ ($T=$Co, Ni)

David W. Tam, Yu Song, Haoran Man +22

We use neutron diffraction and muon spin relaxation to study the effect of in-plane uniaxial pressure on the antiferromagnetic (AF) orthorhombic phase in BaFe${}_2$As${}_2$ and its Co-…
