Resumen:
We analyse the role played by vortex dimensionality in structural transformations induced at the surface of bulk Bi2Sr2CaCu2O8 (extremelyanisotropic) and NbSe2 (moderately anisotropic) vortex crystals interacting with two-dimensional square pinning structures. The observation ofalternating floating and distorted hexagonal domains induced in the NbSe2 vortex structure contrasts with the square one induced inBi2Sr2CaCu2O8. Despite vortexvortex interaction energy being similar in both materials, the different elastic characteristics and the dissimilarvortex solidification mechanisms are responsible for the plastic and elastic structural transformations detected in Bi2Sr2CaCu2O8 and NbSe2,respectively.
