What information can we gather from bifurcation of Field cooled (FC) and zero field cooled (ZFC) MT curves?

The temperature at which FC and ZFC (MT curves) separate is called blocking temperature. What exactly does it signify? How can we distinguish between a ferromagnet and antiferromagnet after...
