Molecular field coefficients of terbium, dysprosium and holmium iron garnets

Theoretical analysis of the anisotropy of the magnetization of the Ho3+ion in holmium iron garnet single crystals

“…Finally, the calculated values of the magnetization of a Ho 3+ ion in HoIG in the whole temperature range (294-4.2 K) when magnetized along the [111], [110], and [100] directions are listed in Table 5. For comparison the experimental values deduced by Guillot et al [14] Table 5. The values of the calculated and measured magnetic moment of a Ho 3+ ions in HoIG at various temperatures (T = 294 − 4.2 K) along [111] [7] ) m(meas.…”

“…Guillot et al [14] showed that both the values of n 0 and γ in Eq. ( 6) are temperature independent.…”

“…1 and 2 are given as follows. [14] along the [111] direction. Three salient features can be observed in this figure.…”

“…Figure1shows the variation of the calculated spontaneous magnetization (M s ) of the Ho 3+ sublattice in HoIG with temperature when magnetized along the [111], [110], and [100] directions, and the experimental values[14] along the [111] direction. Three…”

Quantum theory of the anisotropy of the magnetic properties of ferrimagnetic holmium iron garnet single crystals

“…Guillot et al [16] showed that both the values of n 0 and γ are temperature-independent. Nevertheless, they also pointed out that the values in the temperature range T < T comp may be different from those in the temperature range T > T comp .…”
