Magnetocrystalline anisotropy and spin reorientation in NdFe{sub 12{minus}x}Mo{sub x} and NdFe{sub 12{minus}x}Mo{sub x}N{sub y} compounds (x = 0.5, 1.0, 2.0, 3.0, 4.0, and y {approx} 1.0)

Spin reorientation transitions have been detected in NdFe{sub 12{minus}x}Mo{sub x} by measuring the temperature dependence of the a.c. susceptibility in the temperature range from 4.2 to 300 K. No spin reorientation was traced in NdFe{sub 12{minus}x}Mo{sub x}N{sub y}. Uniaxial anisotropy was detected in NdFe{sub 12{minus}x}Mo{sub x}N{sub y}. The temperature dependence of the uniaxial anisotropy field of NdFe{sub 12{minus}x}Mo{sub x}N{sub y} and NdFe{sub 12{minus}x}Mo{sub x} has been measured in the temperature range from 170 to about 550 K by using the singular point detection (SPD) technique in a pulsed-field magnetometer. NdFe{sub 11}MoN{sub 1.3} and NdFe{sub 10}Mo{sub 2}N{sub 0.9} can be considered as possible materials for permanent magnet fabrication, however, with less chance to compete with Nd{sub 2}Fe{sub 14}B and/or Sm{sub 2}Fe{sub 17}N{sub x}.
