## Abstract We consider a planar Ising model with an extended defect described by couplings of the form __K__(__r__) = __K__Β·(1 + __A/r__). We determine the spectrum of the corner transfer matrix numerically and analytically and use it to calculate the local magnetization at the defect and the corr
