      abstract     = {We present the phase diagram of magnetic states for films
                      of isotropic chiral magnets (ChMs) calculated as function of
                      applied magnetic field and thickness of the film. We have
                      found a novel magnetic state driven by the natural
                      confinement of the crystal, localized at the surface and
                      stacked on top of the conical bulk phase. This magnetic
                      surface state has a three-dimensional (3D) chiral
                      spin-texture described by the superposition of helical and
                      cycloidal spin spirals. This surface state exists for a
                      large range of applied magnetic fields and for any film
                      thickness beyond a critical one. We also identified the
                      whole thickness and field range for which the skyrmion
                      lattice becomes the ground state of the system. Below a
                      certain critical thickness the surface state and bulk
                      conical phase are suppressed in favor of the skyrmion
                      lattice. Unraveling of those phases and the construction of
                      the phase diagram became possible using advanced
                      computational techniques for direct energy minimization
                      applied to a basic 3D model for ChMs. Presented results
                      provide a comprehensive theoretical description for those
                      effects already observed in experiments on thin films of
                      ChMs, predict new effects important for applications and
                      open perspectives for experimental studies of such systems.},
