• Ultrathin magnetic films
• Magnetocrystalline anisotropy
• Dimensionality crossover
• Monte Carlo simulation
• Critical behaviour

We propose the model which takes account of magnetocrystalline anisotropy effects in thin magnetic films. The dimensionality crossover from two-dimensional monolayer to three-dimensional system in multilayer magnetic films is studied using a Monte Carlo technique. Finite-size scaling is applied for the determination of the critical characteristics as a function of film thickness. The transition to intermediate planar phase is discussed.
