The electrotuic strtrcttrres of' carbon toroids are calctrlated by tl?e Liglnt-birading raaodel. Tlteystrotugly depetad on the toroidal geotaaetry (clairal angle, laeiglat, and radivrs), the rn?rgzaetic fltrx,tlae Zeertaan splitting, and tlae teuaaperatttre, The electronic specific laeat tlaus exIaiTcits tl?e riclazaaagnetic-fltrx ;rrad tet'taperattrre dependet?ce. Tl?e unagnetic-fltrx-dependenat lcehax'ior is characterized by t1'?e pronotrnced Aharou'xov-Bolaraa oscillattions.
