摘要：
We report modification of electrical and magnetoresistive properties for the La2/3Sr1/3MnO3/MgO(100) thin films influenced by high power pulsed (tau congruent to 10 ns) laser radiation (lambda = 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-C and reduced magmetoresistance values in the vicinity of T-C.
