I have read already Dzyallonskii's paper as well Moriyas paper which is the two basic paper discussed and derived the reason of spin canting. However, I am finding it difficult to understand. I do not need any mathematical explanation for my understanding. I just want to know the phenomenological concept behind the spin canting in Hematite. Yes, it is well known that spin canting arises when an isotropic superexchange interaction combined with the Spin-Orbit coupling (SOC). But I fail to have a clear picture about this, means how the SOC gives rise to canting and why it just vanishes below the morin transition in hematite.
