Research Abstract

We have developed fabrication process for the tunnel junctions with sub-micron dimensions using strong correlated oxide films toward the spin torque transfer. La_0.6Sr_0.4MnO_3(50nm) was deposited on the SrTiO3 substrate was patterned into 200nm×160nm by electron beam direct writing method and by Ar ion milling. We applied the pattern fabrication method to the electrolyte-gated field effect transistor(FET) using Nd_0.4Sm_0.6NiO_3 thin films. Fabricated transistors showed the Metal-Insulator Transition by changing electric field at room temperature.
