[en] The magnetic properties of an amorphous ferromagnet, Fe(4.7)Co(70.3)Si(15)B(10), were studied. The purpose of this study was to establish the mean magnetic moment per transition metal (TM) atom in the alloy, and to examine the possible magnetic excitation at higher Q. The experiment was performed at room temperature using the D5 spectrometer. The sample was magnetically saturated in a magnetic field to avoid depolarization effects. The measurement was made using neutrons with wavelength of 0.84 A. The reduced radial distribution function DR(r) derived from the interference intensity function i(Q) gives the correlation function T(r), the radial distribution function RDF(r), and the pair distribution function PF(r). The obtained magnetic moment per TM atom was in agreement with the magnetic moment deduced from bulk magnetization measurement. The D5 spectrometer was arranged in a configuration such that it was a triple axis analogue of Mook's time of flight apparatus. In this configuration, two kinds of magnon-neutron inelastic events are allowed. The most remarkable feature of the results was that polarization dependent (SF) scattering was not observed. A well defined polarization independent (NSF) scattering was observed, which was detected close to the position of the first maximum in S(Q). The counting time involved in a single incident wavelength inelastic scan ranged from 10 to 15 hours, compared with the counting time of about one week used by Mook. (Kato, T.)

[en] Crystallographic and Curie temperature measurements have been made on alloys with compositions DyCsub(x), 0.28< x<0.53. The NaCl defect structure is stable in the approximate composition range 0.33<=x<=0.45. The Curie temperatures show a maximum value of 216 K at x=0.33. (Auth.)

[en] The results of a neutron diffraction experiment on a b.c.c. single crystal of Crsub(0.6)Mnsub(0.4) are analysed in terms of a spherical atom form factor to give a mean magnetic moment per atom of (0.82 +- 0.04) β. The deviations from spherical shape of the spatial distribution of the magnetic moment are explained in terms of a predominantly t₂ symmetry. (author)

[en] The magnetization density in ordered Pt₃Cr has been maeasured by polarized neutron diffraction. The induced Pt moment is small (0.26μsub(B)) and oppositely directed to the large Cr moment of 3.37μsub(B) The magnetization has a delocalized component of -0.07μsub(B). (orig.)
