Investigations on growth and characterization of la09pb01mno3 single crystals and effect of heavy ion irradiation on the physical properties

Abstract

Magnetic properties of solids are vitally important in magnetoelectronics newlinemagnetic data storage communication technologies and many newlineother areas The invention of the giant magnetoresistive GMR magnetic newlinemultilayer composed of transition metals was an important step in making the newlinetechnique amenable to industrial applications In the most straightforward newlineapplication an external magnetic field is used to manipulate materials spin newlineand charge properties and thereby control the electrical current The newlinecorrelation of electrons in a solid produces a rich variety of states typically newlinethrough the interplay between magnetism and electrical conductivity The newlineRe1xAxMnO3 system has newlinereceived considerable attention due to the exhibition of colossal magnetoresistance newlineCMRalong with unusual strong coupling among charge spin newlineorbit and lattice degrees of freedom newline newline
