Magnetic phases in hemoilmenite: Insight from low ...

temperature of hematite in the Allard Lake sample shows that the Morin transition is absent. This can be explained by the presenceoftitanium in the hematite structure since as little as 1% Ti4+ can suppress the Morin transition below 10 K[Ericsson et al.,1986]. The magnetic hyperfinefield in the hemo-ilmenite sample is about 1–2%less than that of
