Description :
Metallic multilayers have attracted much interest due to their interesting magnetic
properties. In present investigation, Pd/Nb/Co tri-layers were deposited on Si (100)
substrate by DC magnetron sputtering. The tri-layer samples were hydrogenated in
hydrogen atmosphere of one bar for different time durations. The samples have been
analysed by XRD, AFM, and FE-SEM for their structural and morphological studies,
respectively. Nb-hydride formation has been observed after hydrogenation as confirmed
by XRD data. The magnetic properties of as-deposited and hydrogenated Pd/Nb/Co trilayer
have been tested at low temperature (5K) using superconducting quantum
interference device (SQUID) magnetometer. Insertion of hydrogen in Pd/Nb/Co tri-layer
system increases the remanent magnetic moment but reduces the saturation magnetic
field. Hydrogenated try-layer system possesses ferromagnetic nature, while an antiferromagnetic
nature has been observed for as-deposited Pd/Nb/Co tri-layer.
