abstract={Results of structural neutron diffraction study and data on the transport and magnetic properties (the linear and nonlinear (second and third order) susceptibilities) are presented for the metallic polycrystal La0.88Mn02.95. This above compound exhibits the paramagnet-ferromagnet (P-F, Tc ≈ 244 K) and insulator-metal (I-M, TIM ≈ 253 K > Tc) phase transitions, and reveals a colossal magnetoresistance near TIM. An analysis of the diffraction data is performed using the rhombohedral space group (R3c) in the temperature range 4-300 K. Below T*≈258 K, the FM clusters appear in the PI matrix undergoing a second-order transition. In contract to the traditionally doped analogs, this compound reveals the clustered state in the high symmetrical rhombohedral phase. The concentration of FM clusters increases under cooling, so that it exceeds the percolative threshold value below TIM, and the sample exhibits a metallic behavior. The T-evolution of the clustered state is unexpectedly found to be very close to that of the insulating La0.88MnO2.91 with the F ground state. It is shown that this leads to a certain restriction on a structure of a FM percolative network forming at TIM. The critical behavior of this system has a complicated character due mainly to the origination of the FM infinite cluster below TIM and its interaction with the PI matrix. © 2010 - STC Institute for Single Crystals.},
