Temperature and electric-field induced phase transitions, and full tensor properties of[011]C-poled domain-engineered tetragonal0.63Pb(

Abstract

The phase-transition sequence of 0.67Pb(Mg1/3Nb2/3)−0.37PbTiO3 (PMN-0.37PT) single crystals driven by the electric (E) field and temperature is comprehensively studied. Based on the strain-E field loop, polarization-E field loop, and the evolution of domain configurations, the E field along the [011]C induced phase transitions have been confirmed to be as follows: tetragonal (T) → monoclinic (MC) → single domain orthorhombic (O) phase. As the E field decreases, the induced O phase cannot be maintained and transformed to the MC phase, then to the coexistence state of MC and T phases. In addition, the complete sets of dielectric, piezoelectric, and elastic constants for the [011]C-poled domain-engineered PMN-0.37PT single crystal were measured at room temperature, which show high longitudinal dielectric, piezoelectric, and electromechanical properties (ε33T=10 661, d33 = 1052 pC/N, and k33 = 0.766). Our results revealed that the MC phase plays an important role in the high electromechanical properties of this domain-engineered single crystal. The temperature dependence of the domain configuration revealed that the volume fraction of the MC phase decreases with temperature accompanied by the reduction of ε33T, d31, and k31 due to the substantially smaller intrinsic properties of the T phase.

“…In recent years, some experimental and theoretical investigations about the crystal and domain structure of M phases were reported [26,[39][40][41][42][43][44], which gave us more insight into the M phases. However, up to date, there is still significant debate about the structure of the M phase.…”

Electric-field tuning of magnetic anisotropy in the artificial multiferroic Fe3O4/PMN–PT heterostructure

“…Generally, the AMR realization of an Fe 3 O 4 single crystal thin film is based on the rigid strain effect of a non-ferroic substrate, which lacks tunability [24][25][26]. In order to in situ modulate the magnetic anisotropy of [27][28][29]. In this multiferroic structure, the tunable Verway transition, resistance switching and even non-volatile state are exhibited by the electric field, besides a high AMR can be achieved below Verwey transition temperature [30][31][32].…”

Modulation of Spin Dynamics in Ni/Pb(Mg1/3Nb2/3)O3-PbTiO3 Multiferroic Heterostructure

“…Moreover, Ni is also an ideal material for extensive applications in sensors due to its high temperature stability, anticorrosion, and abrasive resistance [23][24][25][26][27]. Ni/0.7Pb(Mg1/3Nb2/3)O3-0.3PbTiO3 (PMN-PT) singlecrystal is a well-known piezoelectric material, which is desired for FM/FE heterostructures because of its giant anisotropic piezoelectric coefficients and low loss tangents [28][29][30][31][32]. Enlightened by the accomplishment of above, we devoted exploring E-field dominate magnonics.…”
