摘要

The effects of electric field on the magnetization and Hall resistivity were investigated in a laminated composite consisting of Ni_(43)Mn_(41)Co_5Sn_(11) alloy and Pb(Mg_(1/3)Nb_(2/3))O_3-PbTiO_3 ferroelectric single crystal. Upon applying an electric field (3 kV/cm) on the single crystal, the change of Hall resistivity in the alloy is up to 45%. The co-action of magnetization change and the different carrier concentration between the martensitic and austenite phases of alloy, which result from the stress-induced martensitic transformation, are responsible for the electric field-modulated Hall resistivity.
