Fe3+ is evenly distributed among the tetragonal and octahedral sites and is aligned antiparallel while Fe2+ is found exclusively on the octahedral site, resulting in a net magnetic moment of mneaagrnlyet4it μeBi.s It is generally considered that the orbital component of this net magnetic ...
A dependence of the iron moment on the composition of the second nn shell is suggested by the Mssbauer spectra. A combined analysis of magnetization and Mssbauer data rules out spin-glass-like behavior, which may be suspected from the anomalies observed in the temperature dependence of the ...
1–5 The correlation between atom size, by various measures, and magnetic moment has long been noted.6 This correlation is readily seen by comparing the atomic concentrations of the first, second and third transition series elements as shown in Fig. 1, where the densities for the second and ...
Furthermore in I4/mmm and DO22 structures the atomic magnetic moment of Fe1 reverses near the critical pressure. At a pressure of 43 GPa, the micro-ferrimagnetic property in DO22 structure becomes apparently strengthened while its volume increases rapidly. The lattice dynamic calculation shows that...
For the 2Σ+ ground states of the ions Li2+, Li2, and Be2+, the dependence of the magnetic moment (parametrized by g-shifts) on the bond length R was studied at the ROHF level. The Δ g-values were calculated via a perturbative approach (complete to second order in Breit-Pauli int...
The abrupt decrease of the magnetic moment around 155 K in Fig. 3c indicates a first order magnetic phase transition not yet known, but likely related to the competition between the perpendicular anisotropic energy and the thermal agitation energy. As the bulk FGT single crystal also shows a ...
Spectra show a single hyperfine magnetic component, where the angle between the net magnetic moment and the direction of the external field is close to 90°. The most likely spin arrangement is a slight deviation from a collinear antiferromagnet, resulting in a weak ferromagnetic moment....
