ResumoA Mössbauer spectroscopic study is reported on a series of titanium-substituted hematites, (Fe1-xTix)2O3 with x < 0.025. It is found that, even in powder samples, Ti influences the Morin transition (TM) quite strongly. One percent of Ti is enough to depress TM below 10 K and this is likely true for a homogeneous sample with 0.5% of Ti too. The magnetic ordering temperature lowers with Ti-content.
