cond-mat0411100 | in order to understand a crucial role of orbital degree of freedom in the magnetic structure of recently synthesized neptunium compounds nptga@xmath0 ( t = fe , co , and ni ) , we propose to discuss the magnetic phase of an effective two - orbital model , which has been constructed based on a @xmath1-@xmath1 coupling s... | 132 |
1208.2037 | we derive the fundamental parameters ( temperature and luminosity ) of 107619 _ hipparcos _ stars and place these stars on a true hertzsprung russell diagram . this is achieved by comparing bt - settl model atmospheres to spectral energy distributions ( seds ) created from _ hipparcos _ , _ tycho _ , sdss , denis , 2ma... | 156 |
