| Abstract: | The critical properties of the three-dimensional frustrated Heisenberg model on a layered triangular lattice with variable interplane exchange interaction have been investigated by the replica Monte Carlo method. All main magnetic and chiral critical exponents have been calculated. It is found that a decrease in the interlayer exchange leads to crossover from the three-to two-dimensional critical behavior. |
