From the neutron diffraction measurements it is concluded that below the Néel temsperature of 392 K the intermetallic compound Mn 3 B 4 becomes antiferromagnetic. At this stage only the Mn(2c) atoms are magnetic. Below 226 K the Mn(4g) atoms also become magnetically ordered and deform the collinear antiferromagnetic structure to a spiral structure, with an angle of 157.5°, which at lower temperature gradually develops to a collinear antiferromagnetic structure again. The saturated magnetic moments are 2.92 μ B for the Mn(2c) atoms and 0.44 μ B for the Mn(4g) atoms.
