摘要
(111) epitaxial (Mn, Zn)Fe2O4 thin film and yttria-stabilized zirconia (YSZ) buffer layers were deposited on the gate area of metal oxide semiconductor (MOS) transistor by pulsed laser deposition (PLD) using a KrF excimer laser at room temperature. Rectangular-shaped (Mn, Zn)Fe2O4 films were fabricated by wet chemical etching and liftoff processes. Films with a composition (molar ratio) of Mn:Zn:Fe=20:5:75 had a saturation magnetization value of 420 emu/cm(3) after annealing at 800degreesC for 1 hour. The effect of remanent magnetization on the drain current - drain voltage (I-D-V-D) characteristics of MOS transistor was examined. (Mn, Zn)Fe2O4 films on the gate area of the MOS transistors modified the channel of field effect transistor (FET) channel by Hall effect(1)). When the sign of remanent magnetization changed, Hall effect changes the conductance of drain current (I-D).
