Head Melnichuk I.A., Registration Date 01-03-2004 Organization Donetsk National University popup.description2 The dependences of the sputtering yield of magnetoresist LaCaMnO on energy (10 - 30 keV), angle of incidence of Ar+ ions and temperature of a target (20 - 700?С) have been researched. The model of changes of a surface composition of manganites at high irradiation doses has been developed . The temperature dependences of intensity of spectrum lines Mn I 403.1 nm, La I 625.0 nm, Ca I 422.7 nm, Ca II 393.4 nm of optical radiation has been studied at sputtering (Ar+, E = 20 keV) of magnetoresist LaCaMnO and compounds La2O3, CaCO3. The substitution of lanthanum and samarium atoms by atoms of alkali metals in manganites with a perovskite structure has been researched by X – ray method, the crystalline structures of solid solutions are improved and their heat parameters are determined.
