TL;DR: In this article, the first experimental evidence of room temperature direct spin polarized injection in sexithienyl (T 6 ), a prototypical organic semiconductor, from colossal magnetoresistance manganite La 0.7 Sr 0.3 MnO 3 (LSMO), was reported.

TL;DR: In this paper, a straightforward electrochemical method for fabricating sharp cobalt tips was described for those scanning tunneling microscopy (STM) experiments where the focus is on magnetic properties of the surface and the spin polarized (SP) tunneling current is the relevant property.
Abstract: Here we describe a straightforward electrochemical method for fabricating sharp cobalt tips. Such tips are particularly useful for those scanning tunneling microscopy (STM) experiments where the focus is on magnetic properties of the surface and the spin polarized (SP) tunneling current is the relevant property, such as in SPSTM and SP scanning tunneling spectroscopy.

TL;DR: In this article, a spin-valve device has been realized by using two colossal magnetoresistance (CMR) half metallic electrodes separated by the organic semiconductor, T 6, for channel lengths lower than 140 nm.
Abstract: The combined use of highly correlated solids opens the possibility to explore new phenomena and to generate new hybrid devices for Spintronics. We have recently demonstrated the spin injection of carriers into an organic semiconductor, sexithienyl (T 6 ). A spin-valve device has been realized by using two colossal magnetoresistance (CMR) half metallic electrodes separated by the organic semiconductor. The total magnetoresistance as large as 30% was detected for channel lengths lower than 140 nm.
