The electron spin resonance in nearly amorphous carbon has been studied. Amorphous carbon was produced by arc evaporation of spectroscopic pure graphite in argon atmosphere. Carbon deposits were collected and measurements performed without exposing samples to the air, as well as after admission of a
Carbon films deposited on Pyrex, silica and alumina substrates have free spin concentrations similar to those found for chars. The results of heat treatment show that a maximum in the spin concentration occurs at a heat treatment temperature of about 150ยฐC and that when silica and alumina substrates
