Magnetic phase diagram of Ce(CuxRh1-x)(2) Si-2

Magnetic, thermal and transport measurements on Ce(CuxRh1-x)(2)Si-2 are pre sented, The obtained phase diagram shows a rapid decrease of the magnetic o rder on the Rh rich-side. as determined by magnetic susceptibility measurem ents, followed by a region without magnetic order for x > 0.2. In this regi on, the electronic specific heat coefficient increases moderately up to 0.2 J/mol K-2 for x = 0.8. evaluated at 0.5 K. Around 5 K a small anomaly is ob served in the 0.8. As a function of doping, a maximum develops below 10 K i n the electrical resistance. specific heat for 0.4 less than or equal to x less than or equal to 0.8. As a function of doping, a maximum develops belo w 10 K in the electru=ical resistance. Particularly, at x = 0.8, the temper ature of the maximum of the electrical resistance slope coincides with the anomaly observed in the specific heat. (C) 2001 Elsevier Science B.V.
