      abstract     = {Magnetic induction mapping in the transmission electron
                      microscope using phase contrast techniques such as off-axis
                      electron holography and differential phase contrast imaging
                      often requires the separation of the magnetic contribution
                      to the recorded signal from the electrostatic contribution.
                      When using off-axis electron holography, one of the
                      experimental approaches that can be used to achieve this
                      separation is to evaluate half of the difference between
                      phase shift images that have been recorded before and after
                      turning the sample over. Here, we introduce a
                      cartridge-based sample mounting system, which is based on an
                      existing on-axis tomography specimen holder and can be used
                      to turn a sample over inside the electron microscope,
                      thereby avoiding the need to remove the holder from the
                      microscope to turn the sample over manually. We present
                      three cartridge designs, which are compatible with all pole
                      piece designs and can be used to support conventional
                      3-mm-diameter sample grids, Si3N4-based membrane chips and
                      needle-shaped specimens. We make use of a wireless
                      inclinometer that has a precision of 0.1° to monitor the
                      sample holder tilt angle independently of the microscope
                      goniometer readout. We also highlight the need to remove
                      geometrical image distortions when aligning pairs of phase
                      shift images that have been recorded before and after
                      turning the sample over. The capabilities of the
                      cartridge-based specimen holder and the turning approach are
                      demonstrated by using off-axis electron holography to record
                      magnetic induction maps of lithographically-patterned soft
                      magnetic Co elements, a focused ion beam milled hard
                      magnetic Nd-Fe-B lamella and an array of four Fe3O4
