Elasticity, fluctuations and vortex pinning in ferromagnetic superconductors: A "columnar elastic glass"

A. M. Ettouhami, Karl Saunders, L. Radzihovsky +1

We study the elasticity, fluctuations and pinning of a putative spontaneous vortex solid in ferromagnetic superconductors. Using a rigorous thermodynamic argument, we show that in…
