Abstract

Single crystals of (Eu_1-xBa_x)O have been grown in a molten barium-magnesium metal flux at temperatures up to 1000 °C, producing single crystals of (Eu_1-xBa_x)O with barium doping levels ranging from x=0.03 to x=0.25. Magnetic measurements show that the ferromagnetic Curie temperature T_C correlates with the Ba doping levels, and a modified Heisenberg model was used to describe the stoichiometry dependence of T_C. Extrapolation of the results indicates that a sample with Ba concentration of x=0.72 should have a T_C of 0 K, potentially producing a quantum phase transition in this material.
