TLDR
In this article, the magnetic properties of TiFe x Co 1-x have been measured at temperatures between 4.2 and 300 K and interpreted in terms of a weak itinerant electron ferromagnet model.Abstract:
Magnetic properties of TiFe x Co 1- x have been measured at temperatures between 4.2 and 300 K. For the compositions of 0.4≦ x ≦0.8 they are interpreted in terms of a weak itinerant electron ferromagnet model. The slope in the M 2 versus H / M curves rapidly increases with decreasing of iron concentration, which is in good agreement with the result expected from the electronic specific heat coefficient.read more

Magnetic properties of crystallineand amorphous alloys: A systematic discussion based on the Rhodes-Wohlfarth plot
TL;DR: In this paper, the Rhodes-Wohlfarth plot has been used to analyze over a hundred magnetic materials and to distinguish an itenerant from a localized approach, and independent evidence as to the appropriateness of the relevant approach is briefly discussed for many of the materials listed and suggested as a relevant for others.
Journal ArticleDOI
The invar problem
TL;DR: A review of the magnetic and magneto-elastic behavior of both classical and novel materials having Invar characteristics is given in this article, which is reasonably consistent with the view that they are weak itinerant ferromagnets and allows consistent application of the Landau-Ginzburg theory in which all coefficients are given explicitly in terms of energy band and itinerant electron interaction parameters.

F. Acker,R. Huguenin +1 more
TL;DR: In this paper, the authors take the Landau theory of phase transitions as the basis of a simple model where the alloy consists of an homogeneous matrix interacting with a few superparamagnetic clusters.

Magnetovolume effects in itinerant electron ferromagnets
TL;DR: In this article, the enhancement factor due to magnetovolume coupling in the compressibility, high-field susceptibility and forced volume magnetostriction was estimated from the experimental data for various itinerant electron ferromagnets.

P. Rhodes,E. P. Wohlfarth +1 more
TL;DR: In this article, the Curie-Weiss constant and the saturation magnetization of a wide variety of ferromagnetic substances are used to calculate respective values for the numbers of magnetic carriers, q$\_c$ and q$ \_s$.

Exchange‐Enhanced Paramagnetism and Weak Ferromagnetism in the Ni3Al and Ni3Ga Phases; Giant Moment Inducement in Fe‐Doped Ni3Ga
TL;DR: In this paper, the shape of the reciprocal magnetic susceptibility vs temperature curves measured between 4.2° and 300°K is of the Stoner type and suggests for these alloys a density-of-states curve varying appreciably in the Fermi region leading to a low effective energy.

Magnetic Isotherms in the Band Model of Ferromagnetism
D. M. Edwards,E. P. Wohlfarth +1 more
TL;DR: In this paper, the spin wave contribution to low temperature magnetization is considered in the limits of strong and very weak ferromagnetism, and a simple equation for the magnetic isotherms is obtained in this limit and shown to be valid over a wide temperature range.

Theory of Itinerant Ferromagnets Exhibiting Localized-Moment Behavior above the Curie Point
TL;DR: In this paper, the authors used a functional integral formulation of the theory of itinerant ferromagnets above the Curie point and showed that for strong Coulomb interaction $U$ there are localized moments exhibiting a characteristic Curie-law susceptibility with the correct free spin-textonehalf{} limiting value of the curie constant.
