Westudy the local vortex vortex interaction force of vortex structures f i nucleated in Bi 2 Sr 2 CaCu 2 O 8 d sampleswith different types of point and correlated pinning centers We compute f i from images with large fields of viewof the vortex structure from 1000 to 15000 vortices obtained via magnetic decoration experiments Theobserved structures are frozen at T T irr ( during the field cooling processes previous to perform in themagnetic decoration experiments 1 T irr ( of each sample is obtained from local Hall probe magnetometrymeasurements We calculated the probability density functions of the components of f i at several fields for each sample
