Magneto-mechanical Coupling in Thermal Amorphous Solids

, 2018
Standard approaches to magneto-mechanical interactions in thermal magnetic crystalline solids involve Landau functionals in which the lattice anisotropy and the resulting magnetization easy axes are taken explicitly into account.

Stretched exponential behavior in remanent lattice striction of a (La,Pr)$_{1.2}$Sr$_{1.8}$Mn$_{2}$O$_{7}$ bilayer manganite single crystal [PDF]

, 2004
We have investigated the time dependence of remanent magnetostriction in a (La,Pr)$_{1.2}$Sr$_{1.8}$Mn$_{2}$O$_{7}$ single crystal, in order to examine the slow dynamics of lattice distortion in bilayered manganites. A competition between double exchange

Magnetostriction in an array of spin chains under magnetic field

, 2005
We consider an array of XX spin-1/2 chains coupled to acoustic phonons and placed in a magnetic field. Treating the phonons in the mean field approximation, we show that this system presents a first order transition as a function of the magnetic field ...

Tailoring nano-heterogeneity to enhance magnetostriction in Goss grain-oriented Fe81Ga19 alloy thin sheets by aging treatment

Journal of Materials Research and Technology
The magnetostriction of Fe–Ga thin sheets can be significantly improved by secondary recrystallization, but the effect of the nano-heterogeneity on the magnetostriction of Fe–Ga thin sheets with preferred texture is still an open question.

Correlation between linear magnetostriction and magnetocaloric effect in the Fe7Se8 single crystals

Materials Research Express, 2022
The effect of the change in size under the influence of an applied magnetic field (magnetostriction) was studied in Fe _7 Se _8 single crystals. It was shown that a systematic change in the unit-cell constants, induced by an external magnetic field and ...

Thermodynamic evidence for valley-dependent density of states in bulk bismuth

, 2014
Electron-like carriers in bismuth are described by the Dirac Hamiltonian, with a band mass becoming a thousandth of the bare electron mass along one crystalline axis.
