Shear instabilities of a vortex lattice in layered superconductors Article uri icon

abstract

  • We study possible vortex-lattice structures in highly layered superconductors for the magnetic field parallel to the layers. We found instabilities of two different kinds. (1) When the magnetic field is large the shear modulus is exponentially small, and one can expect the vortex lattice to melt in-between the layers. (2) For low magnetic fields, on the other hand, several new types of lattices with almost same energies can be formed instead of an usual triangular array. © 1991.
