ABSTRACTThe effect of in-plane strain on the magnetic anisotropy of [110]-oriented epitaxial TbFe2 films was studied. DC magnetron cosputtering was used to grow epitaxial TbFe2(110) films on A12O3(1120) substrates with an epitaxial Nb(110) buffer layer. Torque magnetometry showed that the films had uniaxial anisotropy, and the torque curves were used to determine the magnetic anisotropy constants of the films by analyzing the rotational hysteresis loss. Film strain was measured using synchrotron radiation. The film strain and anisotropy measurements confirm that the uniaxial anisotropy results from tensile strain in the TbFe2(110) films. This agrees with theoretical calculations of magnetic anisotropy which show that tensile strains can induce a uniaxial anisotropy in TbFe2(110) films.

Amorphous Ce[Formula: see text]Fe[Formula: see text]O[Formula: see text] nanowire arrays with diameters about 100 nm were fabricated in porous anodic aluminum oxide (AAO) template channels by chemical co-precipitation assisted by suction filtration. Ce[Formula: see text]Fe[Formula: see text]O[Formula: see text] nanowire arrays have distinct magnetic anisotropy behavior, and the axis parallel to the nanowire is magnetically “easy.” The magnetic properties of Ce[Formula: see text]Mn[Formula: see text]O[Formula: see text] and Ce[Formula: see text]Fe[Formula: see text]Mn[Formula: see text]O[Formula: see text] nanowire arrays were investigated to compare with Ce[Formula: see text]Fe[Formula: see text]O[Formula: see text] nanowire arrays. The fluorescence spectra of Ce[Formula: see text]Fe[Formula: see text]O[Formula: see text] nanowires arrays mixed with Eu, Tb, Sm showed that their emission intensity displays regular change with the increase of the mole fraction of mixture. The emission intensity reached maximum with increasing of Eu or Sm-mixing from 2 mol% to 10 mol% at 591 nm, 709 nm or 607 nm, then decreased gradually. However, there is no obvious influence to fluorescence of Tb mixed Ce[Formula: see text]Fe[Formula: see text]O[Formula: see text] nanowire arrays, only one visible weak emission peak is present at 486 nm.
