On the hierarchy of the characteristic lengths of nanowires magnetization
Usingcomputer simulationof magnetizationinapolycrystalline ferromagnetic nanowire,we demonstrate the occurrence of the characteristic spatial scale in the distribution of magnetization unrelated to the domain wall or crystallite size. This is the stochastic domain size. We show that this length not ...

Zeros in partition function and critical behavior of disordered three dimensional Ising model
We used a Monte Carlo simulation of the structurally disordered three dimensional Ising model. For the systems with spin concentrations p =0.95, 0.8, 0.6 and 0.5 we calculated the correlation-length critical exponent by finite-size scaling. Extrapolations to the thermodynamic limit yield �(0.95) =...
