Spin Fluctuation Theory Versus Exact Calculations,ssfully applied to Invar systems. In particular we calculate the order parameter and the volume for this model from the exact free energy and from an application of the spin fluctuation theory which we adjust to this model. We find rather large discrepancies in the temperature behaviour.使增至最大 发表于 2025-3-30 15:58:10

Magnetoelasticity and Isotope Effect in Ferromagnets,s based on the phenomenon of magnetoelasticity. The parameters of the approach are determined from the experimental data for Fe, Ni and for Fe-Ni, Fe-Ni-Mn, Fe-Pt Invar alloys. Quantitative calculations of the contributions of acoustic phonons to the Curie constant, Curie temperature and to the isot迅速成长 发表于 2025-3-31 03:56:07

The Phase Diagram of the Kondo Lattice,due to the competition between the long range RKKY interactions, I(R.-R.), and the local negative s-f exchange, J, responsible for the Kondo effect: the ground state can be either magnetic or nonmagnetic depending on the relative strength of these interactions, λ =T./I (T.≈1/pexp(1/pJ) is the characBRINK 发表于 2025-3-31 11:46:00

Atomic Volume Effect on Electronic Structure and Magnetic Properties of UGa3 Compound,erature range 64–300 K. This study reveals a pronounced pressure effect on magnetic properties of UGa. and the measured pressure derivative of the Néel temperature is found to be d../d.=-1.1 K/kbar. In order to analyze the experimental magnetovolume effect, to be specific dln ./dln ., the volume dep过时 发表于 2025-3-31 18:34:47
