Abstract
The effects of fast-neutron irradiation on the magnetic-field-induced elect ronic phase transition in graphite have been investigated; the fast-neutron irradiation introduces lattice defects in graphite, some of which act as a ccepters. It has been found that the transition temperature is lowered with increasing concentration of lattice vacancies introduced Ly neutron irradi ation. The suppression of the transition temperature can be interpreted as a manifestation of tie pair-breaking effect by charged lattice vacancies, s imilar to magnetic impurities in a superconductor. This supports the existi ng theoretical interpretation of the field-induced transition being a densi ty-wave transition.
