Abstract

The half-metallic characteristic of Co2FeAl Huesler alloy films in Co2FeAl/Pb(Mg1/3Nb2/3)O3-PbTiO3 heterostructure was controlled by different substrate temperatures during deposition. The evolution of microstructure shows the B2 ordering degree of Co2FeAl thin film increase with the substrate temperature decreasing from 550 °C to 480 °C during deposition, which can be verified by anisotropy magnetoresistance measurement. Moreover, the result measured by rotating-angle ferromagnetic resonance demonstrates B2 ordering degree of Co2FeAl thin film controlled the change of symmetry of magnetic anisotropy. In addition, the loop-like curve of magnetic resonance field/linewidth versus electric field exhibits the non-volatile behavior, which can be attributed to the 109° ferroelectric domain switching of PMN-PT substrate. This result can provide opportunities for magnetization control in multiferroic devices.
