Study of obliquely deposited 57Fe layer on organic semiconductor (Alq3); interface resolved magnetism under x-ray standing wave

Interface magnetism in Fe/Alq3 bilayer; interface resolved nuclear resonance scattering studies

“…Along with the isotope sensitivity GINRS technique can be made depth selective under the xray standing wave condition [25,35,36]. For this purpose, we have used 57 This 2D simulation is the distribution of x-ray filed intensity inside the waveguide structure.…”

“…X-rays can be made available to probe the interface effectively by confining the X-rays intensity in a specific region along the depth using X-rays standing wave (XSW) generated for waveguide structure [32][33][34]. In some previous study [25,[35][36][37][38], the effectiveness of XSW for depth profiling of the interface using the grazing incidence nuclear forward scattering technique is demonstrated. By varying incidence angles, magnetic information was gained from the intended region.…”

“…OSC=Alq3, rubrene, C60, pentacene-T6 etc.) are available in the literature, where significant efforts have been made to understand the spin injection, manipulation, and detection in organic spin valve (OSV), the effect of barrier layer at interface and electron structures at interfaces 3,8,9,15,16 . Although most of the studies pointed out the importance of the top electrode interface (FM/OSC) in terms of magnetism, results are missing, where the depth profiling of the top magnetic electrode (FM/OSC) was done properly with an aim to study interface magnetism.…”
