Effect of lanthanum on growth-induced anisotropy in LPE bubble garnet films

Effect of lanthanum on growth-induced anisotropy in LPE bubble garnet films

Growth-induced anisotropy, Ku, in bubble garnet films containing La and Eu or Sm has been found to be anomalous compared to that produced by Eu or Sm and smaller ions such as Y or Lu. In (111) films of Eu-La or Sm-La, Ku is essentially zero. However, in (110) and (100) films of the same composition,...

Zusammenfassung:Growth-induced anisotropy, Ku, in bubble garnet films containing La and Eu or Sm has been found to be anomalous compared to that produced by Eu or Sm and smaller ions such as Y or Lu. In (111) films of Eu-La or Sm-La, Ku is essentially zero. However, in (110) and (100) films of the same composition, Ku is large and of opposite sign from Eu-Y or Sm-Y films, as would be expected if ionic radii alone determine the site selectivity. The unusual behavior of La has been used to produce (110) bubble garnet films with appreciable growth-induced orthorhombic anisotropy.
