研究了电场对由Ni43Mn41Co5Sn11合金和PbTiO3铁电单晶组成的层状复合材料的磁化强度和霍尔电阻的影响。在单晶上施加3KV/cm的电场后，合金的霍尔电阻率变化可达45%。应力诱发马氏体相变引起的磁化强度变化和马氏体相与奥氏体相之间载流子浓度的不同共同作用是产生电场调制霍尔电阻率的原因。
The effects of electric field on the magnetization and Hall resistivity were investigated in a laminated composite consisting of Ni43Mn41Co5Sn11alloy and Pb(Mg1/3Nb2/3)O3–PbTiO3ferroelectric single crystal. Upon applying an electric field (3kV/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.
