Spin Fluctuations in Ferromagnetic Metals : Temperature Variation of Local Moment and Short Range Order
TLDR
In this article, the magnetic properties of typical ferromagnetic metals are discussed on the basis of the previously developed unified theory with the use of relatively small number of physical parameters including the longitudinal and transverse (exchange) stiffness constants for the spin fluctuation.Abstract:
Magnetic properties of typical ferromagnetic metals are discussed on the basis of the previously-developed unified theory with the use of relatively small number of physical parameters including the longitudinal and transverse (exchange) stiffness constants for the spin fluctuation From the analysis of existing experimental results we discuss on the temperature variation of the amplitude of local spin fluctuation (local moment) and the degree of short rang order in Pd 2 MnSn, Fe 3 Pt, CoS 2 , Fe, Co, Ni and MnSiread more

Neutron Scattering Investigation of Itinerant Electron System Fe2P
TL;DR: In this article, Fe 2 P is of the hexagonal C-22 type structure and exhibits c-axis ferromagnetism below 130 K. In the intermediate range between 130 K and 217 K, the canted ferromagnetic properties with a uniform component along the c -axis M 0 and a staggered component in the c-plane M Q appear, and the first order transition takes place at T c =217 K from the Canted Ferromagnetic to paramagnetic properties, leading to the existence of a giant short range order up to T =3 T c

Recent progress in the theory of itinerant electron magnetism
TL;DR: A review of recent theoretical investigations toward unified understanding of magnetism in narrow-band electron systems is given in this article, where the classical controversy between the itinerant and localized models have been resolved into a more general and well-defined problem of spin density fluctuations in a general sense.
