Coupling of single, double, and triple-decker metal-phthalocyanine complexes to ferromagnetic and antiferromagnetic substrates

Introduction to Electronic Properties and Dynamics of Organic Complexes as Self‐Assembled Monolayers

“…Among the techniques that give access to magnetic moments, the X-ray magnetic dichroic spectroscopy measurements with elemental sensitivity is widely used in the case of paramagnetic SAM [18,19,38].…”

Recent progress in organic spintronics

“…This has been studied in some detail for various π-conjugated molecules adsorbed on ferromagnetic surfaces. The most common experimental techniques to probe the interface electronic and magnetic structure are x-ray magnetic circular dichroism (XMCD) [93][94][95], spin-polarized scanning tunneling microscopy (SP-STM) [90,[96][97][98], spin-polarized metastable de-excitation spectroscopy(SP-MDS) [99][100][101], spin-polarized ultraviolet photoelectron spectroscopy (SP_UPS) [102][103][104], and spin-resolved two-photon photoemission (SR-2PPE) [77]. Modeling is typically done with density functional theory (DFT) [89,95,97,98,[104][105][106][107][108][109].…”

“…with a flat ring structure) π-conjugated molecules have been studied. In particular, metal-phthalocyanines (Pc's) and porphyrins have received a considerable amount of attention [89,93,96,97,99,[103][104][105]107]. The metal ions in these metallo-organic molecules typically have unpaired spins, which are found to couple to the ferromagnetic substrate via the exchange interaction.…”

“…The metal ions in these metallo-organic molecules typically have unpaired spins, which are found to couple to the ferromagnetic substrate via the exchange interaction. The presence of such ions allows for element specific magnetic probing with XMCD [93]. This technique relies on the excitation of core-level electrons with circularly polarized x-rays into unoccupied states to probe the magnetic polarization of the conduction band.…”

Spintronic effects at nickel-graphene interfaces

“…At the interface between the materials phenomena like orbital hybridisation and charge transfer can greatly influence the transport of spins across the interface. Spin polarised microscopy and spectroscopy techniques have shown these effects to be typically spin dependent, resulting in a hybrid interface with magnetic properties that are quite different from those of the bulk ferromagnet (Djeghloul et al, 2013;Lach et al, 2012;Rizzini et al, 2014;Sun et al, 2014;Suzuki et al, 2002Suzuki et al, , 2004Tran et al, 2013). It is a topic of active study how this effects the spin transport across the interface Kawahara et al, 2012;Raman et al, 2013;Schmaus et al, 2011;Steil et al, 2013).…”
