Controllable electric field tuning of anisotropic magnetic response of Ni/PMN-PT heterostructures

Tunable Magnetic Domain Patterns in Thickness-Gradient Nickel Films on Flexible PDMS Substrates

“…The direction of stripe domains can be controllably changed by an applied current based on the interaction between spin waves and domain walls. , The distribution of magnetic domains can also be regulated by changing the temperature . For flexible magnetic films with large magnetostriction coefficients, the modulation by stress loading is one of the most effective methods due to the magnetoelastic coupling effect. , The previous studies have shown that the direction and morphology of magnetic domains can be modulated by bending the magnetic films simply. , When an electric field is applied to a piezoelectric substrate, the strain of the film can also be altered by the inverse piezoelectric effect thereby modulating the magnetic domain structure . Similarly, the nucleation/annihilation of azurite ions can be modulated by strain due to the shape memory effect of the TiNiNb substrate, whereas thermally driven phase transitions present on the substrate can cause tensile strain in the film .…”
