dc.descriptionWe present electron spin resonance (ESR) measurements at X-Band frequency (ν=9.5 GHz) in powdered single crystal of the half-Heusler antiferromagnet GdPdBi grown using a Bi-flux method. In the paramagnetic state, a single Gd 3+ Dysonian ESR line is observed with a nearly temperature independent g-factor of ≈1.99(2). On the other hand, the ESR linewidth ΔH increases non-linearly with decreasing temperature, indicating that the dominant relaxation mechanism occurs via Gd3+ spin-spin interaction. Approaching the AFM transition at TN ≈13 K, the Gd3+ ESR line shifts to higher fields due to the emergence of short-range AFM correlations. Complementary data from macroscopic measurements such as magnetic susceptibility, heat capacity and electrical resistivity measurements provide further details about the global macroscopic physical properties of the GdPdBi compound. © 2013 Elsevier Ltd.
