Spin Dynamics of the S = 2 Magnet in a Cubic Crystal Fieldtric; consequently the two modes are strongly mixed at long wavelengths and the low frequency response may be expressed in Debye form with a relaxation time that diverges at T.. Results are in agreement with dynamic susceptibility theories of Buyers and Lines.Metastasis 发表于 2025-3-23 15:50:01

https://doi.org/10.1007/BFb0011851al-field and the effects of bilinear and quadrupolar pair interactions. At U.2 K excitedstate spin waves have been observed which correspond to transitions from the upper member of the ground-state doublet Γ... The stability of the unusual flopside spin structure is discussed.FER 发表于 2025-3-23 22:47:33

Gene Cooperman,G. Michler,H. Vinckansition in TbSb should be of first order, since the Hamiltonian shows no stable fixed point within the ε-expansion. In pure TbSb we find the critical exponent β = 0.20±0.01 in the region 4×10. < (T.-T)/T.<2×10.. In Tb.Y.Sb the exponent is significantly different, we find a sharp transition with β = 0.37±0.05.皱痕 发表于 2025-3-24 19:35:40
Lecture Notes in Earth Scienceslectrons. The problem of beginning with a very basic Hamiltonian, and recasting it to show localized moments and conduction properties is considered using degenerate perturbation theory. The result is a spin-Hamiltonian of typical form for the localized moments, with conduction electrons as well. AtMri485 发表于 2025-3-25 01:43:24
