Elasticity, fluctuations, and vortex pinning in ferromagnetic superconductors: A columnar elastic glass
Elasticity, fluctuations, and vortex pinning in ferromagnetic superconductors: A columnar elastic glass
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 the idealized case of vanishing crystalline pinning anisotropy the long-wavelength tilt modulus of such a vortex solid vanishes identically, as guaranteed by the underlying rotational …
