“…4) Recent studies revealed that the DE scenario alone cannot explain the whole physics occurring in the manganite system and thereby the interplay among spin, charge, orbital, and lattice should be invoked to render more precise explanations on the CMR phnomenon. [5][6][7] It has been suggested that the magnetic polaron attributable to combined effect of lattice distortions and magnetic clusters is a probable origin of CMR effect, designating that short-range interactions is a crucial factor to be taken. 8) Recently, Dai et al investigated on the low-doped system La 1Àx Ca x MnO 3 (0:15 x 0:3) by means of neutron diffuse scattering technique, revealing that the short-range charge (polaron) couplings persist even in the low temperature regime and affect the electrical transport properties.…”
