Abstract
- We report modification of electrical and magnetoresistive properties for the La<subscript>2/3</subscript>Sr<subscript>1/3</subscript>MnO<subscript>3</subscript>/MgO(100) thin films influenced by high power pulsed ( 10 ns) laser radiation ( = 532 nm). SEM surface study revealed cracks extended along [100] directions and partially melted material at film surface with radiation power increasing. Low field magnetoresistance typical for high quality intergrain junctions has been measured at T < 240 K for the films with laser beam-induced cracks while partial melting of the material resulted increased electrical resistance, lowering of the paramagnetic to ferromagnetic transition temperature T<subscript>C</subscript> and reduced magnetoresistance values in the vicinity of T<subscript>C</subscript>.
