The investigation of the manganites La 2=3 2 x Pr x Sr 1/3 MnO 3 , La 2/3 Sr 1=3 2 x Ca x MnO 3 and La 2=3 ΓΎ x Ca 1=3 2 2x Ag x MnO 3 , which all exhibit Mn 3ΓΎ :Mn 4ΓΎ ΒΌ 2, shows that it is possible to reach high magnetoresistance at room temperature, up to 21% under 1.2 T. These materials are compar

In addition to the dielectric relaxation around 170 K in the cubic structure of Srl\_3x/2LaxTiO 3, a similar relaxation was observed at about 70 K in the tetragonal structure with an activation energy in the range 0.1 3-0.16 eV which increases as x in Srl\_3x/2La,TiO 3 varies from 0.60-3.00 at %.

## Abstract Epitaxial manganite thin films with very high room temperature magnetoresistance (MR) values are designed by tuning several parameters as composition, microstructure, substrate material, and film thickness, simultaneously. The resulting La~0.7~Ca~0.2~Ba~0.1~MnO~3~/Ag composite thin film
