The effective magnetic moment mu_eff of the Eu spins in the paramagnetic state from 100 to 300 K is found from static magnetic susceptibility measurements to be enhanced by about 7% compared to the value expected for spectroscopic splitting factor g = 2, and the saturation moment at high applied fields H and low temperatures T is also sometimes enhanced.
