Thertnoelectrjc and t)aerntomagnetic properties have been investigated of asingle crystal graphite irradiated with fast neutrons of a total dose of 3 x 10" nvt,and after stzbsequent]y annealed at 250'C and 14O0'C. The Seebeck coefficients(.5') of the post-irradiated as well as the 250'C-annealed crystals are whollypositive at te?avperatures (7) between 300 K and 4.2 K, while the characteristicphonon drag anonaaly still survives in the S vs T diagram, consisting of positiveand negative conaponents located arotund 25 K and 40 K respectively. Annealingat ]400'C, whereby the radiation-induced vacancies have mostly been recovered,naakes the S vs T cu rve not IIIUCII different from that of the unirradiated graphite,except for the dotmblet strtxcture of the phonon drag dip. The presence of a mag..netic field enlxances the therntoelectricity in positive and/or negative direction.The Nernst-Ettingshausen coefficient nteasttred at 6 k0e is also accompaniedby tlte PIIOIIOII drag anoxnaly having the doublet structure.
