ESR investigation of the spin dynamics in (Gd_{1-x}Y_{x})_2PdSi_{3}

J. Deisenhofer, H. -A. Krug von Nidda, A. Loidl +1

We report electron-spin resonance measurements in polycrystalline samples of (Gd_{1-x}Y_{x})_2PdSi_{3}. We observe the onset of a broadening of the linewidth and of a decrease of t…
