“…Beside the study of polymer systems, the second field in which NR has proved to be a powerful tool is the study of magnetic thin films and multilayers: exchange coupling in superlattices [31,32], exchange bias coupling between ferroand anti-ferromagnetic layers [33][34][35][36][37][38][39], exchange spring effects between soft and hard magnetic layers [40,41], ultra-thin films [42][43][44]. The neutron has a spin which makes it a very sensitive probe to the magnetisation of thin films.…”

“…magnetic (FM) metals, but their trihydrides are weakly antiferromagnetic (AFM) insulators. [10] It is also possible to tune the long-range exchange coupling of FM films through hydrogen uptake in paramagnetic spacer layers: Fe 3 /V x superlattices can be switched from AFM to FM with hydrogen loading and vice versa. The change of the interlayer coupling is not simply due to the expansion of the non-magnetic V spacer layer, but to the distortion of its Fermi surface.…”

Trivalent rare earth hydrides stabilized in thin film form demonstrate spectacular optical and electronic properties. A thin film of YHx or LaHx can be transformed rapidly from metal to insulator, from shiny mirror to transparent window, simply by changing the surrounding hydrogen gas pressure or an electrolytic cell potential at room temperature (RT). At low temperatures, in‐situ doping is not possible in this way as hydrogen cannot diffuse. However, our finding of persistent photoconductivity under ultraviolet illumination permits tuning through the T = 0 metal–insulator transition and reveals the important role played by strong electron correlations. We discuss the optical, electronic, magnetic, and structural properties of switchable mirrors from both the technological and scientific perspectives.

“…Size effects may produce relevant modifications in the known magnetic phases of RE elements because of nonuniform magnetic structure (191) induced by the lower coordination near the surfaces. Thickness effects on the magnetic ordering temperatures, magnetoelastic stresses and electric charge anomalies in Ho thin films were studied [2][3][4][5].…”

Influence of Thickness and Magnetic Field on Magnetic Ordering Temperatures in Holmium Thin Films

et al. 2008

Influence of thickness and magnetic field on magnetic ordering temperatures is reported. The X-ray diffraction of Ho films confirmed their preferential crystal orientation and revealed diffraction peaks originating from the hcp structure of Ho and those from inessential holmium dihydride content. Secondary ion mass spectroscopy showed a very homogeneous distribution of holmium in thin films. Electrical resistance measurements on Ho films in the thickness range from 98 nm to 215 nm showed a "knee-like" resistance anomaly near the T N . The T N value of these films decreased with decreasing film thickness. Magnetic field applied parallel to the thin film plane caused an increasing suppression of the T N value up to 5 K with increasing flux density value up to 5 T.
