Magnetic Nano-Ring and Single Domain

We have patterned magnetic nano-ring and single domain structures of Ni on (011) PMN-PT substrate, and used MFM and X-PEEM technique to characterize the magnetic domain movement in patterned Ni nanostructures. We have achieved a permanent 90° rotation in the

Giant Tunable Piezoelectric Remanent Strain and its Application on ME-RAM

We have demonstrated a Ni/PMN-PT ME heterostructure providing an electric-field-induced switching between two reversible and permanent magnetic easy axes perpendicular to each other. The tunable remanent strain defines the initial magnetoelastic anisotropy while the giant strain hysteresis reversibly and permanently

Giant piezoelectric strain hysteresis and novel ferroelectric properties of (011) [Pb(Mg1/3Nb2/3)O3](1-x)-[PbTiO3]x (PMN-PT, x≈0.32) single crystals

The ferroelectric (011) [Pb(Mg1/3Nb2/3)O3](1-x)-[PbTiO3]x (PMN-PT, x≈0.32) single crystals show two giant reversible and stable remanent strain states and tunable remanent strain properties are achieved by properly reversing  the electric field from the depolarized direction. The unique piezoelectric strain response, especially
