| Outline of Final Research Achievements |
Recently, a new research field of spintronics utilizing molecular materials has attracted much attention. In this study, we have fabricated molecular spintronics devices, in which tris(8-hydroxyquinolinato) aluminium (Alq3) organic molecules are sandwiched between Co and Ni75Fe25 ferromagnetic electrodes, and investigated their ac impedance characteristics. As a result, the spin signal observed at low temperature can be qualitatively explained by the equivalent circuit model analyzed by Cole-Cole plot obtained from ac impedance characteristics.
