Abstract The INTEGRAL and SWIFT satellites detected a large number of galactic X-raysources above 20keV,among which virgul6-7% identified as accreting white dwarfbinaries. Among known systems most harbour asynchronously rotating magneticprimaries, suggesting that this formerly small subclass could be an importantcontributor to the galactic X-ray binary populations. However, most newlydiscovered sources are proposed as magnetic cataclysmic variables throughoptical spectra. XMM-Newton demonstrated unique potential to infer their truenature through the detection of X-ray pulses and study of broad-band spectra. Wepropose 6 new sources that, if all confirmed as magnetics, will increase by 35%the hard X-ray sample enabling a true census of the first volume-limited sample

Mission Description The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
