 note = {The 3rd Suzaku international Conference "Energetic Cosmos : from Suzaku to ASTRO-H" (June 29-July 2, 2009. Grand Park Otaru Hotel), Otaru, Hokkaido Japan, In order to search for a second "white dwarf pulsar" (Terada et al. 2008) as a possible particle accelerator of cosmic-rays via rotating magnetic field, an X-ray observation of a promising magnetic cataclysmic variable, AM Her, was performed with Suzaku satellite in November 2008. The object was in the very low state according to the AAVSO optical magnitude, and the X-ray flux during the Suzaku observation was two order of magnitude lower than that taken with Chandra in 2004 in low state. Clear spin modulation was observed in the soft energy band, having the same spin phase as that in the high state with ASCA due to the thermal-plasma modulation, whereas shallower spin modulation was observed in harder energy bands. The X-ray spectra can be described by two kinds of model; double thermal plasmas or thermal plasma with power law component, representing thermal or non-thermal origin in hard X-ray band, respectively. The best fit parameters in the former model show too high temperature as > 11 keV and too low abundance as 0.06 +/- 0.02 solar. The latter model represents a 1.1 +/- 0.1 keV plasma with an abundance of 0.8(sup +0.4)(sub -0.2) solar, and a non-thermal component with the photon index of 2.2 +/- 0.2. If the latter model is true, AM Her can be a second white dwarf pulsar with the non-thermal X-ray flux of 4.1 x 10(exp -29) erg/s at 91 pc distance in 0.5 - 10 keV band, which is similar to the AE Aqr case of 6.6×10(exp -29) erg/s at 102 pc., Meeting sponsors: The University of Tokyo, The Institute of Physical and Chemical Research, The Japan Society for the Promotion of Science, 資料番号: AA0064574072, レポート番号: JAXA-SP-09-008E},
