From the INTEGRAL and Swift surveys a significant fraction (virgul5% and 6%respectively) of hard X-ray sources were found to be asynchronous magneticCataclysmic Variables (CVs), most of the Intermediate Polar (IP) type. We aim tocontinue our identification programme of newly discovered CVs that arecandidates to be magnetic. Only with the detection of periodic X-ray pulses andthe study of their broad-band X-ray spectra it will be possible to firmlyidentify their true IP nature. This will provide insights in the physics of thisemerging class of accreting compact objects, recently proposed to be animportant population of galactic X-ray sources.

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.
