New magnetic cataclysmic variables from the sloan digital sky survey

Two new faint (g similar to 18-22) cataclysmic variables ( CVs) from the Sloan Digital Sky Survey ( SDSS) are confirmed as being strongly magnetic systems from time- resolved optical spectroscopy and spectropolarimetry. SDSS J0921+2038 shows circular polarization that varies between negative and positive values, and at one phase displays a series of overlapping cyclotron emission peaks that characterize a magnetic plasma with B=32 MG and kT approximate to 10 keV. The polarization of SDSS J1333+1437 reaches V/I=15% and its spectrum displays the blue continuum and strong H, He emission-line component often found in the polar class of magnetic CV. Phasing of photometry, polarimetry, and radial velocity measurements for SDSS J1333+1437 indicates a (spin/orbit) period of 2:2 +/- 0.1 hr.
