Effects of Lanthanum Doping on Structural Evolution, Morphological Features, and Flux Pinning in FeSe0.5Te0.5 Single Crystals with Machine Learning Assistance

Abstract Single crystals of La x Fe 1− x Se 0.5 Te 0.5 ( x = 0, 0.02, 0.04, 0.06, 0.08) were grown using the self-flux method. A systematic investigation of the effects of La addition revealed changes in the lattice parameters, with the lattice parameter a decreasing and the latt...
