  1. Physical quantities for \(\hbox {Fe}_{81}\hbox {Ga}_{19}\) (5 nm) and \(\hbox {Fe}_{80.9}\hbox {Ga}_{18.9}\hbox {La}_{0.2}\) (5 nm) thin films grown on PMN/PZT(0.3mm) substrates. The reported physical quantities are the anisotropy character (Anisotropy), the maximum value of the coercive field (\(H_{\textrm{c}}^{\textrm{max}}\)), the converse magneto-photostrictive coupling coefficient maxima (\(\alpha _{\textrm{CMP,max}}^\mathrm {410 \, nm}\)), the relative change of the resonance field under the converse magneto-photostrictive effect (\(\Delta H_{\textrm{res}}\)/\(H_{\textrm{res}}^\textrm{off}\)), the linewidth of the resonance line (Linewidth). The gain (Gain) is equal to \(\frac{X^{\textrm{FeGaLa}}-X^{\textrm{FeGa}}}{X^{\textrm{FeGa}}}\), with \(X^{\textrm{FeGaLa}}\) being the value of a given physical quantity for \(\hbox {Fe}_{80.9}\hbox {Ga}_{18.9}\hbox {La}_{0.2}\) and \(X^{\textrm{FeGa}}\) being the value of the same physical quantity for \(\hbox {Fe}_{81}\hbox {Ga}_{19}\). PMN-PZT is the (011)-Pb(\(\hbox {Mg}_{1/3}\hbox {Nb}_{2/3}\))\(\hbox {O}_3\)-Pb(Zr,Ti)\(\hbox {O}_3\) substrate.
