Giant Magnetoelastic Coupling in a Metallic Helical Metamagnet

Giant magnetoelastic coupling in a metallic helical metamagnet.

Using high resolution neutron diffraction and capacitance dilatometry we show that the thermal evolution of the helimagnetic state in CoMnSi is accompanied by a change in interatomic distances of up to 2%, the largest ever found in a metallic magnet. Our results and the picture of competing exchange and strongly anisotropic thermal expansion that we use to understand them sheds light on a new m...

An ab initio study of the magnetocrystalline anisotropy and magnetoelastic coupling of half-metallic CrO2

First-principles density functional calculations of the total energy, magnetic moments and magnetocrystalline anisotropy energy (MAE) of CrO2 as a function of both volume and uniaxial strain along the c-axis have been performed. The highly accurate all-electron full-potential linearized augmented plane wave method and the generalized gradient approximation to the exchange–correlation potential ...
