Magnetization of R2Fe13.6Si3.4 (R = U, Lu) single crystals under pressure

The magnetoelasticity of the U2Fe13.6Si3.4 and Lu2Fe13.6Si3.4 single crystals has been studied by magnetization measurements along the principal axes under hydrostatic pressure. The contributions from the Fe and U sublattices to the magnetic moment, magnetic anisotropy and magnetoelasticity of U2Fe13.6Si3.4 are discussed.
