In order to investigate the electronic configuration on CuO2 plane,Fe 57 Mi~ssbauer effect is measured for the samples (Lal-xSrx)zCul-yFeyO4. The analysis of Isomer shift reveals that s-electron density at Fe 3' nucleus increases with increasing carrier density. From the analysis of quadrupole split
