Static and Microwave Properties of Amorphous Magnets Near Saturation
Eugene M. Chudnovsky, Dmitry A. Garanin
Static and dynamic properties of magnetically soft amorphous ferromagnets have been studied analytically and numerically within random-field and random-anisotropy models. External…
New approach to designing functional materials for stealth technology: Radar experiment with bilayer absorbers and optimization of the reflection loss
Jaume Calvo de la Rosa, Aleix Bou Comas, Joan Manel Hernandez +4
Microwave power absorption by a two-layer system deposited on a metallic surface has been studied in the experimental setup emulating the response to a radar signal. Layers contain…
Scaling of Static and Dynamical Properties of Random Anisotropy Magnets
Dmitry A. Garanin, Eugene M. Chudnovsky
Recently observed scaling in the random-anisotropy model of amorphous or sintered ferromagnets is derived by an alternative method and extended for studying the dynamical propertie…
Melting and Freezing of a Skyrmion Lattice
Dmitry A. Garanin, Jorge F. Soriano, Eugene M. Chudnovsky
We report comprehensive Monte-Carlo studies of the melting of skyrmion lattices in systems of small, medium, and large sizes with the number of skyrmions ranging from to o…
