Abstract: Surfaces of magnets and ultrathin magnetic films are a source of rich physics due to (i) a reduction of the coordination number enhancing magnetism, (ii) substate orientations motivating magnetic frustration, and (iii) an inversion symmetry breaking giving rise to chiral magnetic interactions. All this together gives rise to magnetic interactions that cannot be solely explained by the conventional Heisenberg model. Starting from simple ideas and gedankenexperiments I cover recent works on new magnetic phases at surfaces including Gd(0001), Fe/Rh(111), Fe/Ir(111), rare earth on graphene etc, with surprising results cover chiral, non-collinear, and skyrmionics textures.
