Pressure effects on the resistivity of TmS

Quasi hydrostatic pressure measurements of the resistivity of a single crystal of TmS are reported. The resistivity σ is reduced by pressure P over the full range studied (up to 28 kbar and down to liquid He). It goes through a maximum near 10K and decreases logarithmically for higher temperatures. Both this behavior and the reduction of the InT slope by P can be explained in a model of resonant scattering as previously done for Ce compounds. The Néel temperature TN, marked by a small anomaly in σ, increases with P in accordance with previous susceptibility results. © 1981.
