Roles of Crystal Fields in Magnetic Superconducting Rare-Earth Rhodium Borides

  • S. Maekawa
  • C. Y. Huang


Many interesting magnetic, as well as, superconducting properties, have been reported in a series of rare earth (RE) rhodium borides RERh4B4. Nonmagnetic LuRh4B4 and YRh4B4 are high Tc superconductors with Tc ∿ 11.5 K and ∿ 11.3 K, respectively.1 On the other hand, RERh4B4 with R = Gd, Dy, Tb and Ho are ferromagnetic metals.1 Furthermore, ErRh4B4 2,3 and the pseudoternaries such as Er1−xGdxRh4B4,4 Er1−xHoxRh4B4,5 Ho1−xLuxRh4B4, 6 Gd1−xYxRh4B4,4,7 Er1−XTmxRh4B4,8 and Er1−xYxRh4B4 9 are reentrant superconductors in proper ranges of x; the superconducting states change to ferromagnetic normal states at low temperatures.
