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

“…In the present case, it is found to be 21 Å (±2Å), depicting the nonmagnetic contribution at the interface 55,56,57,58 . In contrast to the literature where a reduction in magnetism was reported due to the formation of the alloy at the Fe/Alq3 interface and its antiferromagnetic coupling with the metallic Fe layer 13 , the formation of the magnetically dead layer at the interface in the present case could be related to the diffusion at the interface and or the appearance of paramagnetic nanoclusters. Recently, A. G. Khanderao et al have studied a similar bilayer structure ( 57 Fe/Alq3), demonstrating the capability of GINRS under XSW.…”

“…Furthermore, penetrated metal atoms in OSC can react chemically and affect its transport properties. In extreme cases, top FM layer atoms penetrate deep into the organic layer 11,12,13,14 , causing a conductive pathway to the bottom electrode and leading to the spin valve failure.…”
