The <Néel temperature> marks loss of long-range <antiferromagnetism>. A <Curie temperature> concerns <ferromagnetism> or <ferrimagnetism>; <magnetic compensation temperature> instead denotes cancellation within an ordered <ferrimagnet>.<Magnetism and the local molecular field by Louis Néel>[§5, pp.324–326; §§8,11–12: ordering versus compensation]{ref}
In the simple collinear description, compare $|\mathbf L|$ across $T_N$, rather than expecting $|\mathbf M|$ to switch from nonzero to zero. Zero-field <magnetization> may be zero on both sides. A nonzero <magnetic susceptibility> is also compatible with <antiferromagnetism>: an applied <magnetic field> can disturb the cancellation. The <uniform response of a two-sublattice Ising antiferromagnet> provides a model calculation.
