  • patterned growth of crystalline y3fe5o12 nanostructures with engineered magnetic shape anisotropy
    Applied Physics Letters, 2017
    Co-Authors: Na Zhu, Houchen Chang, Andrew Franson, Tao Liu, Xufeng Zhang, Ezekiel Johnstonhalperin, Hong X Tang
    Abstract:

    We demonstrate patterned growth of epitaxial yttrium iron garnet (YIG) thin films using lithographically defined templates on gadolinium gallium garnet substrates. The fabricated YIG nanostructures yield the desired crystallographic orientation, excellent surface morphology, and narrow ferromagnetic resonance (FMR) linewidth (∼4 Oe). Shape-induced magnetic anisotropy is clearly observed in a patterned array of nanobars engineered to exhibit the larger coercivity (40 Oe) compared with that of continuous films. Both hysteresis loop and angle-dependent FMR spectra measurements indicate that the easy Axis Aligns along the longitudinal direction of the nanobars, with an effective anisotropy field of 195 Oe. Our work overcomes difficulties in patterning YIG thin films and provides an effective means to control their magnetic properties and magnetic bias conditions.

  • Patterned growth of crystalline Y$_{3}$Fe$_{5}$O$_{12}$ nanostructures with engineered magnetic shape anisotropy
    'AIP Publishing', 2017
    Co-Authors: Na Zhu, Chang Houchen, Franson Andrew, Liu Tao, Zhang Xufeng, Johnston-halperin E., Wu Mingzhong, Tang, Hong X.
    Abstract:

    We demonstrate patterned growth of epitaxial yttrium iron garnet (YIG) thin films using lithographically defined templates on gadolinium gallium garnet (GGG) substrates. The fabricated YIG nanostructures yield the desired crystallographic orientation, excellent surface morphology, and narrow ferromagnetic resonance (FMR) linewidth (~ 4 Oe). Shape-induced magnetic anisotropy is clearly observed in a patterned array of nanobars engineered to exhibit the larger coercivity (40 Oe) compared with that of continuous films. Both hysteresis loop and angle-dependent FMR spectra measurements indicate that the easy Axis Aligns along the longitudinal direction of the nanobars, with an effective anisotropy field of 195 Oe.
