This compound exhibits an insulator-metal (IM) phase transition at TIM̃253 K (above the Curie temperature, TC̃244 K) and reveals colossal magnetoresistance. The crystal structure is found to be rhombohedral, and the space group is R3c. Analysis of magnetic properties shows that at T*̃258 K > TC, isolated paramagnetic clusters occur in the paramagnetic matrix; their concentration increases upon cooling. We observed no noticeable differences between the temperature evolution of the clustered state of this manganite with its insulator-metal transition and in the insulator La0.88MnO2.91. Possible scenarios of the paramagnet-ferro- magnet and I-M transitions in a self-organized clustered structure are discussed. © Allerton Press, Inc., 2011.","funding_details":"Russian Academy of Medical Sciences4.4.1.8","key":"Lazuta2011198","id":"Lazuta2011198","bibbaseid":"anonymous-paramagneticferromagneticandinsulatormetalphasetransitionsinla088mno295-2011","role":"author","urls":{"Paper":"https://www.scopus.com/inward/record.uri?eid=2-s2.0-79955789031&doi=10.3103%2fS1062873811020201&partnerID=40&md5=c33a0d6cf256945f1a623d07d857f4c6"},"metadata":{"authorlinks":{}}},"bibtype":"article","biburl":"https://bio.pnpi.nrcki.ru/wp-content/uploads/2019/12/lbm_2019_10.txt","dataSources":["YYLjupmCazkNqWNEJ"],"keywords":[],"search_terms":["paramagnetic","ferromagnetic","insulator","metal","phase","transitions","88mno2"],"title":"Paramagnetic-ferromagnetic and insulator-metal phase transitions in La 0.88MnO2.95","year":2011}
