A temperature-dependent extended x-ray-absorption fine structure investigation of La 1−x Ca x MnO 3 is presented for the concentration range that spans the ferromagnetic-insulator ͑FMI͒ to ferromagnetic-metal ͑FMM͒ For this range of Ca concentrations the samples are insulating for x = 0.16– 0.2 and show a metal/insulator ͑M / I͒ transition for x = 0.22.
