Notes:
Considerable efforts have recently been made in understanding the magnetic behavior of the rare-earth transition-metal compound Nd2Fe14B, which orders ferromagnetically at Tc=600 K and exhibits a spin-reorientation transition at TSR=135 K. In an effort to obtain direct information on the spin configuration and magnetic ordering in this technologically important compound, we have performed a Nd-145 Mössbauer study on a single crystal of Nd2Fe14B using the 72.5-keV nuclear gamma resonance of Nd-145. The results clearly show that the temperature dependence of the Nd-sublattice magnetization is totally different from that of the macroscopic magnetization, i.e., dropping off far below Tc. The results suggest that the spin-reorientation transition in Nd2Fe14B is driven by an ordering of the Nd sublattice below TSR.
