Abstract

Structure and magnetic characteristics of RE2Fe14B have been determined on powder and single crystal samples, both by X-ray and neutron diffraction. All the magnetic and structural parameters have been measured versus the absorbed hydrogen. Hydrogen acts indirectly on the magnetic structure via the magnetoelastic couplings, but also directly via the “screenning” effect of hydrogen filling interstices between RE and Fe. Results from various techniques as Mossbauer spectrocopy, μ+SR, magnetization measurements… obtained on pure and hydrided samples are reported.
