Abstract
Two-phase epitaxial Ni0.65Zn0.35Al0.8Fe1.2O4 (NZAFO) and BiFeO3 layers were deposited as self-assembled nanobeltlike heterostructures on (110) SrTiO3 single crystal substrates by switching pulsed laser deposition. The magnetic anisotropy and coercivity of the low loss high magnetostriction NZAFO phase were altered by the large shape anisotropy of this nanostructure relative to that of single crystal layers. The self-assembled heterostructures exhibited strong magnetic anisotropy along the in-plane direction, resulting in an ability to tune the coercivity from 2 Oe (single crystal NZAFO layers) to ∼650Oe (nanobelt heterostructure). The geometry of the nanobelt shape has a reflection on magnetic anisotropy: the orientation of the easy axis was altered from the in-plane direction. Rotation of the sample about its [11¯0] direction revealed that the hard magnetic axis was along the [001] with two easy directions at θ=±30°. In-plane rotation about the [110] revealed a strong magnetic anisotropy along [11¯0] and [001], which are the two directions that defined the rectangular shape of the nanobelts. Our findings demonstrate a self-assembled nanobelt heterostructural layer whose spinel ferrite phase coercivity and easy axes can be controlled by nanostructural features, which, in turn, modify the magnetic properties.
