The C14 Nb(Fe89.4Al10.6)2 Laves phase intermetallic compound was investigated by DC magnetization (M) measurements performed in the temperature (T) interval from 20 to 
, under an applied magnetic field (H) ranging between 50 and 
. Magnetization curves were recorded in the field-cooled (FC) and in the zero-field-cooled (ZFC) modes. They clearly showed an irreversible character that vanished at 
. Both magnetization curves exhibited well-defined peaks around 
whose positions were H-independent, so they were identified as the compound's Néel temperature. The existence of the irreversibility whose degree decreases with H testifies to a re-entrant character of magnetism in the studied compound. An increase of both 
and 
observed below TN likely indicates a mixed, i.e., ferromagnetic and antiferromagnetic ground magnetic state of the studied system.
