Efficient spin transport through polyaniline

Spin-pump-induced spin transport in a thermally-evaporated pigment-red film

“…Carbon-based molecular materials for the wide possibility of spintronic applications have attracted much attention [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Those are expected as good spin transport materials originating from the weak spin-orbit interaction in the materials.…”

Direct detection of induced magnetic moment and efficient spin-to-charge conversion in graphene/ferromagnetic structures

“…Spin current has the advantage of flowing in both metallic and insulating materials that can be magnetic or nonmagnetic. This features increase the range of spintronics phenomena that are of interest for basic and applied research, such as: (i) spin transport in magnetic insulators and organics materials [12][13][14][15][16][17] ; (ii) spin-to-charge current-conversion in paramagnetic, ferromagnetic and antiferromagnetic metals, as well as in semiconductors [18][19][20][21][22][23][24][25][26][27][28] ; (iii) magnetization manipulation by spin transfer torque (STT) [29][30][31][32][33] ; and spin-charge interplay in two dimensional systems based on the Rashba-Edelstein effect [34][35][36][37][38][39][40] .…”

Spin Transport in Organic Semiconductors

“…The on-going debate about the potential artefacts in conventional vertical organic spin valves such as TAMR can be avoided in spin pumping experiment. The observation of spin to charge conversion in PEDOT: PSS by FMR spin pumping and the more recent observation of spin transport in PBTTT by spin pumping and ISHE of a heavy metal detector have opened up a new avenue to probe spin dynamics in organic materials by using spin pumping technique [61], [62], [145], [146], [147], [148], [149]. This chapter explores the spin transport in a variety of organic semiconductors using tri-layer spin pumping architecture where the organic semiconductor is sandwiched between a ferromagnetic layer under ferromagnetic resonance and a heavy metal detector layer.…”

“…To circumvent these roadblocks associated with electrical spin injection, transport, and detection in organic semiconductors using trilayer and nonlocal architectures, it becomes necessary to use experimental techniques that achieve spin injection without charge injection across an interface. One implementation of such a protocol is based on spin pumping involving the dissipation of angular momentum at a ferromagnetic injector and into a non-magnetic metal or semiconductor layer [158], [159], [62], [145], [146], [160]. Fig 6 .1a shows a schematic of a lateral spin pumping architecture and measurement configuration that achieves this.…”
