Kristallicheskaya I Magnitnaya Struktura Manganitov La1-Xsrxmno3-

Dannaya kniga posvyashchena issledovaniyu struktunogo i magnitnogo fazovogo sostoyaniya v stekhiometricheskikh i anion-defitsitnykh manganitakh La1-xSrxMnO3-. Zameshchennye manganity so strukturoy perovskita nachali izuchat' bolee 50 let nazad. Interes k ikh izucheniyu voznik iz-za togo, chto eti tverdye rastvory, poluchaemye na baze oksidov margantsa, imeyut bol'shoe raznoobrazie strukturnykh, magnitnykh i transportnykh svoystv. V to zhe vremya, issledovaniya manganitov vyyavili novoe yavlenie, nazvannoe kolossal'nym magnitnym soprotivleniem. Interesnymi ob"ektami dlya izucheniya vzaimosvyazi mezhdu izmeneniyami kristallicheskikh i magnitnykh svoystv manganitov yavlyayutsya stekhiometricheskie La1-xSrxMnO3 i osobenno anion-defitsitnye La1-xSrxMnO3- soedineniya. V dannykh soedineniyakh nablyudayutsya mnozhestvo raznoobraznykh strukturnykh i magnitnykh faz v zavisimosti ot urovnya legirovaniya shchelochnozemel'nym metallom i v zavisimosti ot urovnya defitsita kisloroda.
