      abstract     = {PETRA IV is an upgrade project planned to replace the
                      Synchrotron light source PETRA III. The main objective is to
                      reduce the horizontal emittance to 20 pmrad. This nominal
                      emittance will be achieved by a hybrid six bend achromat
                      lattice(H6BA). To fulfill the requirement of this lattice,
                      three different types of permanent dipole magnets will be
                      used which include a combined-function dipole-quadrupole
                      magnet with both longitudinal and transverse gradient (DLQ).
                      The use of permanent magnet material for the
                      combined-function dipole-quadrupole magnets is particularly
                      useful for achieving a compact design, but also for reducing
                      power consumption during operation. This paper presents the
                      overall progress in this DLQ development, the expected
                      magnetic field characteristics obtained from 3D Radia
                      simulations, and advanced design details like the cross-talk
                      with neighboring quadrupole magnets. The status of the
                      present prototype activities is also discussed.},
