The highly iron-doping to the rutile TiC, nano-crystals up to Fe/Ti = 0.2 (Ti(0.833)Fe(0.167)O(2-delta)) was investigated by magnetic and high-pressure annealing study. The magnetic data clearly confirmed the substitution and absence of ferromagnetic order. Instead, presence of anti-ferromagnetic interactions was detected. The high-pressure annealed pellets were revealed highly electrically insulating, reflecting electrical nature of the doped crystals. The result provides a great contrast to what was observed for the thin film form of the doped ferromagnetic TiO(2).
