Abstract
The superconducting (Tc and magnetic ordering (Tm) critical temperatures in RExY1-xRh1.1Sn3.6 (RE = Er, Ho) have been determined by magnetic measurements. For RE = Er superconductivity appears for any value of x, and reentry to a magnetically ordered state for x ≥ 0.6, while for RE = Ho the compound becomes either superconducting or magnetically ordered, and is expected to remain paramagnetic for x near 0.5. Theories of Abrikosov-Gorkov and Roshen-Ruvalds are used to explain Tc(x) , leading to I2N(0)G=0.23 K and 0.8 K for Er and Ho respectively. Comparison of Tm(x) with the theory of Oguchi-Obokata gives respectively J = 0.30 K and 0.96, using a Heisenberg model with z = 6.
