Notes:
Assuming the sample to consist of ferromagnetic metallic (FMM) particles with a volume fraction (f ) randomly distributed over the paramagnetic insulating background, Monte Carlo simulations of electrical conductivity show excellent fits to the data measured in (La1−xYx)2/3Ca1/3MnO3 (x=0, 0.1 and 0.2). We find that the transition to metallic state occurs as the f reaches a percolation threshold, suggesting that the percolation of FMM domains is responsible for the observed insulator–metal transition. © 2001 American Institute of Physics.
