Budget: 1.200.000 lei,

Objectives of the project:

1)synthesis and determination of electronic phase diagram for a new (Ln,Ln’)_1-xA_xMn_1-yM_yO_3+d (Ln,Ln’=rare earth, A=Sr,Ca,Ba,Pb; M=Cu,Cr,Co,V,Sc)
establish of a correlation between transport characteristics, magnetic structure and electronic phase composition

Technical objectives of project:

establish of the influence of alkali oxidic additives on phase composition of manganites,
design and obtain of bulk and thin films magnetoresistive manganites,
achievement and testing of some experimental models of the magnetic field/temperatures sensors, working into 250 -350 K, based on the (Ln,Ln’)_1-xA_xMn_1-yM_yO_3+d .
