Weak magnetism phenomena in heavy-fermion superconductors: selected $\mu$SR studies

A. Amato, M. J. Graf, A. de Visser +3

The behavior of the so-called weak moment antiferromagnetic states, observed in the heavy-fermion superconductors UPt${}_3$ and URu${}_2$Si${}_2$, is discussed in view of recent $\mu$SR re…
