Paper Abstract
We report electric field control of nanoscale magnetic domain pattern transformation processes due to the converse
magnetoelectric effect in a magnetoelectric device. The magnetoelectric device is a Ni-microdot/PZT-film bi-layer
heterostructure. Due to the converse magnetoelectric effect, nanoscale magnetic domain (i.e. dot-domain/pseudo-single-domain/
short-stripe-domain/vortex-core) in the central region of a Ni microdot is controlled under an electric field (1.6
MV/m). The electric field induced domain-pattern transformation process (i.e. deformation and rotation of the nanoscale
domain in the central region of the Ni microdot) is observed with the magnetic force microscopy. Upon removal of the
electric field, the deformed/rotated nanoscale magnetic domain-pattern/vortex-core returns to its original state, i.e.
reversible domain-pattern-transformation/vortex-core-motion.
