Synthesis and Study of Reactive Mesogen in a Spin Valve Structure
The hyperfine and spin–orbit coupling interaction are weak; due to these, organic materials are proposed to be excellent spin transport layer. In organic spin valve, reactive mesogen is used as the spacers, which have more advantages such as solution processing, higher mobility, and large area fabrication. The FeCo and NiFe dissimilar top ferromagnetic (FM) electrodes are used for spin injection and detection causing magneto resistance (MR) effect. The MR ratio was 3.2% at 50?K. Depending on various temperature, the MR behaviors were observed. This is the first reported spin MR effect in organic spin valve using reactive mesogen (RM) as a spacer layer. The results indicate that the HMPC (2,6-Bis 4-hydroxy propyloxy-3-methoxy benzaldehyde cyclohexanone) (RM) can be used as spin transport materials and provide clear for future organic based spintronics studies.
