Abstract: Magnetic (χ), transport (Ï), and heat capacity (Cm) properties of CeIrSi are investigated to elucidate the effect of geometric frustration in this compound with trillium type structure because, notwithstanding its robust effective moment,
μeff≈2.46μB, this Ce-lattice compound does not undergo a magnetic transition. In spite of that it shows broad Cm(T)/T and χ(T) maxima centered at Tmax≈1.5 K, while a ÏâˆT2 thermal dependence, characteristic of electronic spin coherentfluctuations,is observed below Tcoh≈2.5 K. Magnetic field does not affect significantly the position of the mentioned maxima up to ≈1 T, though χ(T) shows an incipient structure that completely vanishes at
μ0H≈1 T. Concerning the ÏâˆT2 dependence, it is practically not affected by magneticfield up to μ0H=9 T, with the residual resistivity Ï0(H) slightlydecreasing and Tcoh(H) increasing. These results are compared with thephysical properties observed in other frustrated intermetallic compound.
