Magnetic properties of Nd 2 (Fe 1-x M x ) 14 B measured on single crystals (M =Al, Cr, Mn and Co)

Temperature dependence of magnetization and anisotropy field of Nd2(Fe1-xMx)14B, where M = Al(0 \leq x \leq 0.10), Cr(x=0.05), Mn(x=0.05) and Co(0 \leq x \leq 1), have been measured on single crystal samples grown by the floating zone melting technique. Substitution with M for Fe in Nd2Fe14B has been found to shift the spin reorientation transition temperature toward low temperatures and, at the s...
