  We study the equilibrium and dynamical properties of skyrmions in thin films
of chiral magnets with oblique magnetic field. The shape of an individual
skyrmion is non-circular and the skyrmion density decreases with the tilt angle
from the normal of films. As a result, the interaction between two skyrmions
depends on the relative angle between them in addition to their separation. The
triangular lattice of skyrmions under a perpendicular magnetic field is
distorted into a centered rectangular lattice for a tilted magnetic field. For
a low skyrmion density, skyrmions form a chain like structure. The dynamical
response of the non-circular skyrmions depends on the direction of external
currents.
