| Abstract: | Some recent results of magnetic and transport measurements on single crystals of the Er(Ni,Co)2B2C series will be presented and discussed, in particular, possible evidence of a superzone gap formation at the antiferromagnetic phase transition in pure ErNi2B2C, detailed anisotropic H–T phase diagrams and their modification with Co doping, and enhancement of the superconducting critical current in the weak ferromagnetic phase. |
