Outline of Final Research Achievements

We investigated and demonstrated a thermal field response of an Artificial magneto-electric material Cr2O3 /Cr2O3±x/LiNbO3/Cr2O3±x/Cr2O3(CR-LN) multilayer using Spin Seebeck tunneling effetc. We got three results as follows; 1)A voltage was generated by the application of the thermal field in CR-LN system. 2) The voltage was degcresesd by the application of magenetic fields. 3) The polarization of tunneling layer play an important role for the thermal generated voltage. These three results we can conclude the thermal generated voltage in CR-LN system was closely related the tunneling effect, spin wave spin current, and ferroelectric polarization.
