A series of Nd₂Fe_17-xMn_x solid solutions with x values between 0 and and 6 were prepared and analyzed using magnetic measurements, neutron diffraction, and Mössbauer spectroscopy. All of the Nd₂Fe_17-xMn_x samples crystallized in the Th₂Zn_17-x-type rhombohedral structure. The lattice parameters and unit cell volumes decrease with increasing manganese content up to ∼ x equal to 2, and then increase for higher manganese content. The magnetizations of Nd₂Fe_17-xMn_x decrease with increasing manganese content and Nd₂Fe_17-xMn_x is paramagnetic …
