Magnetic-susceptibility measurements of the Magn\'eli phases of the Ti-O system show a change from weak covalent bond formation, through antiferromagnetic to paramagnetic-like behavior with increasing oxygen concentration. The reciprocal molar susceptibility plotted versus temperature indicates collective electron effects in all phases except TiO1.50 and TiO1.67. These exhibit noncooperative and cooperative semiconductor-to-metal transitions, respectively.
