Effects of magnetic and non-magnetic doping on the vortex lattice in MgB${}_2$

E. R. Louden, S. Manni, J. E. Van Zandt +8

Using small-angle neutron scattering we have studied the vortex lattice in superconducting MgB${}_2$ with the magnetic field applied along the $c$-axis, doped with either manganese o…
