Title: Esr Of Gd3+ In Y1 - X - Yybxgdyinni4

Abstract: Electron spin resonance (ESR) results of Gd3+ diluted in (Y1 - xYbx)InNi4 for 0 ≤ x ≤ 0.8 are reported. It is found that for x = 0 the linewidth presents the usual temperature linear behavior and a negative g-shift. As x is increased the residual linewidth also increases, and a non-linear temperature dependence is observed. An additional relaxation channel through the RKKY interaction is suggested to explain the results. The Yb exchange parameter is determined as function of the concentration. © 2001 Elsevier Science B.V. All rights reserved.
