Magnetism and magnetic anisotropy in UGa2

MRS Advances, 2020
We investigate whether first-principles calculations with an improved description of electronic correlations can explain the large magnetic moments and the strong magnetocrystalline anisotropy in the ferromagnetic compound UGa2. The correlations are treated within a static mean-field approximation DFT+U combining the density functional theory (DFT ...

Magnetic Anisotropy of Heterostructures

2007
The chapter provides a detailed introduction to magnetic anisotropy of ferromagnetic ultrathin films and its analysis by ferromagnetic resonance on a tutorial level. While the microscopic origins of the magnetic anisotropy as well as recent developments in its theoretical description are shortly discussed, emphasis is put on a phenomenological ...

Magnetic anisotropy of RE-magnets

IEEE Transactions on Magnetics, 1987
A brief survey is given of the most recent results in the study of magnetic anisotropy in RE intermetallic compounds of interest for permanent magnet applications. Among these the 1:5 and 2:17 phases are those that have received the largest attention in the past years, and their properties are understood to a satisfactory level.

Interfacial anisotropy in magnetic superlattices

Physical Review Letters, 1987
We have observed large discrepancies between the dc magnetization and ferromagnetic resonance (FMR) magnetic anisotropy in Mo-Ni superlattices. We show that higher-order anisotropy is present in both measurements and develop an analysis by which the first-order and second-order energies can be treated independently.

Surface and step magnetic anisotropy

Physical Review B, 1994
Cu(11n) surfaces vicinal to Cu(001) are characterized by (001) terraces separated by monoatomic steps. Growth of thin epitaxial magnetic films on such terraced substrates, e.g., Co/Cu(1 1 13), leads to unexpected magnetic anisotropy associated with the surface steps.

Anisotropy in Magnetism

2001
The enormous research on magnetic properties of ultrathin films and nanostructures produces also new activities in the fundamental understanding of the magnetic anisotropy energy (MAE) and the anisotropy of the orbital magnetic moment/atom. The pseudomorphic growth of Fe, Co, Ni on metallic and non-metallic substrates can change the nearest neighbor ...

Theory of magnetic interface anisotropy

Physical Review B, 1993
Calculations show that the surprising ``orientation independence'' of the Co/Pd interface anisotropy found experimentally is an accidental consequence of the precise degree of strain exhibited by this system and is not generally expected. The conclusions are supported by the good agreement between experiment and our electronic structure calculations ...

Shape anisotropy of magnetic multilayers

Physical Review B, 1992
It is shown that the shape-anisotropy energy density of magnetic multilayers with cylindrical symmetry about the {ital z} axis normal to the film is {minus}2{pi}{ital M}{sub {ital s}}{sup 2}({ital z}{bar )} in the continuum limit, where {ital M}{sub {ital s}}{sup 2}({ital z}{bar )} is the average of the square of saturation magnetization {ital M}{sub ...

Shape anisotropy of magnetic heterostructures

Physical Review B, 1996
General expressions for the magnetic self-energy and the shape anisotropy of heterogeneous bodies have been derived. Heterogeneous bodies of arbitrary shape are assumed to be composed of coherently packed fine particles of arbitrary shape. Our mean-field approach is compared with the previous approaches to the problem of dipolar interactions specific ...
