Five different magnetic phase transitions have been identified and characterized in stoichiometric 
Nd

NiO

 by means of magnetic-susceptibility and isothermal-magnetization measurements. A collinear antiferromagnetic ordering of 
Ni
2
+
 magnetic moments exists between 
T
N

≊320 K and 
T
c

≊130 K where an orthorhombic-to-tetragonal structural phase transition occurs. In this temperature range, 
Nd
3
+
 ions follow a simple paramagnetic Curie-Weiss-like behavior, while a weak ferromagnetic component appears below 130 K. An internal magnetic field on the 
Nd
3

 ions develops with this structural phase transition. Two additional transitions are observed at 
T

≊68 K and 
T

≊45 K which are characterized by a sudden increase of the weak ferromagnetic component. Finally, a peak of the differential susceptibility at 
T
N
2
≊11 K marks a long-range antiferromagnetic ordering of the 
Nd
3

 ions. The internal magnetic field acting on the Nd ions was evaluated to be 5.2 T in the 20 K–
T

 temperature range.
