WebSep 6, 2024 · Abstract. In heavy-fermion compounds, the dual character of f electrons underlies their rich and often exotic properties like fragile heavy quasiparticles, a variety of magnetic orders and unconventional superconductivity. 5f-electron actinide materials provide a rich setting to elucidate the larger and outstanding issue of the competition … WebExtended to a lattice of magnetic ions, the Kondo effect likely explains the formation of heavy fermionsand Kondo insulatorsin intermetallic compounds, especially those involving rare earth elements such as …
