Effect of strain-induced anisotropy on magnetization dynamics in Y(3)Fe(5)O(12) films recrystallized on a lattice-mismatched substrate

We report on the correlation of structural and magnetic properties of Y(3)Fe(5)O(12) (YIG) films deposited on Y(3)Al(5)O(12) substrates using pulsed laser deposition. The recrystallization process leads to an unexpected formation of interfacial tensile strain and consequently strain-induced anisotro...

description We report on the correlation of structural and magnetic properties of Y(3)Fe(5)O(12) (YIG) films deposited on Y(3)Al(5)O(12) substrates using pulsed laser deposition. The recrystallization process leads to an unexpected formation of interfacial tensile strain and consequently strain-induced anisotropy contributing to the perpendicular magnetic anisotropy. The ferromagnetic resonance linewidth of YIG is significantly increased in comparison to a film on a lattice-matched Gd(3)Ga(5)O(12) substrate. Notably, the linewidth dependency on frequency has a negative slope. The linewidth behavior is explained with the proposed anisotropy dispersion model.
