Antiferromagnetism and Hidden Order in Isoelectronic Doping of URu${}_2$Si${}_2$

Abstract

We present muon spin rotation ($\mu$SR) and susceptibility measurements on single crystals of isoelectronically doped URu${}_{2-x}$T${}_x$Si${}_2$ (T = Fe, Os) for doping levels up to 50\%. Zero Field (ZF) $\mu$SR measurements show long-lived oscillations demonstrating that an antiferromagnetic state exists down to low doping levels for both Os and Fe dopants. The measurements further show an increase in the internal field with doping for both Fe and Os. Comparison of the local moment - hybridization crossover temperature from susceptibility measurements and our magnetic transition temperature shows that changes in hybridization, rather than solely chemical pressure, are important in driving the evolution of magnetic order with doping.
