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.

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

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
