dc.description.abstractWe report for the first time the 57Fe Mössbauer spectrum of the ternary phase Nd2Fe14B, a technologically important new compound which forms the basis for a new class of high performance light rare earth‐iron permanent magnet materials. From single phase powders we deduce the hyperfine parameters of the iron sublattices in the Nd2Fe14B structure. Spectra of high‐energy product ribbons obtained by a rapid quench process confirm that these permanent magnet materials are comprised predominantly of the Nd2Fe14B phase.en_US

dc.identifier.citedreferenceThe sample was confirmed to be single phase both by optical metallographic analysis of the starting ingot and by x‐ray and neutron diffraction on the powder.en_US
dc.identifier.citedreferenceDetails of the melt‐spinning process are given in Ref. 1. This sample was obtained at a melt‐spinner substrate velocity of 15 m∕s.en_US
dc.identifier.citedreferenceThe full Hamiltonian is given in Ref. 8. This fit assumes that the electric field gradient is parallel to the internal field, and that the electric field gradient tensor is symmetric. Each site can then be described solely in terms of its isomer shift, internal field Hint,Hint, and quadrupole splitting eQVzz/2,eQVzz∕2, where Q is the electric quadrupole moment and VzzVzz is the z component of the electric field gradient.en_US
