Magnetic Characteristics of Ball-Milled Nd2Fe14B - Gd

Mössbauer measurements using ⁵⁷Fe and ¹⁵⁵Gd have been made on samples of ball-milled Nd₂Fe₁₄B in a gadolinium matrix in order to determine the magnetisation of each phase separately. Although magnetometer measurements did not show any coercivity, both measurements showed the phases were in intimate magnetic contact. The spectra of each phase differed considerably from those of the respective original materials and provide information on the conduction electron polarisation through the transferred hyperfine fields.
