The coexistence of short- and long-range forces and the diversity of many competing phases have challenged present electronic models based on regular lattices. The challenge is approached here by invoking the concept of small-world network, whose topology interpolates between regular lattices and random graphs. Magnetic phase transition and percolation transition in these complex networks are studied via Monte Carlo simulations and finite-size scaling analyses. The observed ramified percolative fractals, signified field-induced percolation transition, and enhanced colossal magnetoresistive effects agree with experiments well. © 2006 American Institute of Physics.Fractals; Magnetoresistance; Manganese compounds; Percolation (solid state); Phase transitions; Topology; Complex network; Magnetoresistive effects; Percolation transition; Self-organized manganites; Transition metalsjournal article10.1063/1.23380242-s2.0-33747868948WOS:000240035400062
