- W1990173080 abstract "The ${mathrm{CeIr}}_{1ensuremath{-}x}{mathrm{Rh}}_{x}{mathrm{In}}_{5}$ series exhibits a range of interesting phenomena, including heavy-fermion superconductivity, non-Fermi liquid behavior, and concomitant antiferromagnetism and superconductivity. In the low-Rh concentration range $(0.1ensuremath{leqslant}xensuremath{leqslant}0.5)$, specific heat measurements show a broad anomaly, suggestive of gross phase separation. We have performed x-ray absorption experiments at the $mathrm{Ce}phantom{rule{0.3em}{0ex}}{L}_{mathrm{III}},mathrm{Ir}phantom{rule{0.3em}{0ex}}{L}_{mathrm{III}}$, and $mathrm{Rh}phantom{rule{0.3em}{0ex}}K$-edges as a function of Rh concentration and temperature. X-ray absorption near-edge structure measurements indicate that cerium is close to trivalent in this system, with no measurable change with temperature from 20--300 K, consistent with a heavy-fermion material. Extended x-ray absorption fine structure measurements as a function of temperature from all measured edges indicate the local crystal structure of all samples is well ordered, with no gross phase separation observed, even for samples with $x=0.125$ and $x=0.25$. These results therefore suggest that the anomalous specific heat behavior in the $0.1ensuremath{leqslant}xensuremath{leqslant}0.5$ range have some other explanation, and some possibilities are discussed." @default.
