QCD Origin of Strong Magnetic Field in Compact Stars
  Some magnetic properties of quark matter and a microscopic origin of the strong magnetic field in compact stars are discussed; ferromagnetic order is discussed with the Fermi liquid theory and possible appearance of spin density wave is suggested within the NJL model. Implications of these magnetic properties are briefly discussed for compact stars.
