Abstract

There are two purposes in this study. One is to see the performance of our powder neutron diffractometer, HERMES, for a very heavy neutron absorber, GdB₂C₂. The other is to see the magnetic structure of GdB₂C₂ as a compound of the tetragonal RB₂C₂ family, in which antiferroquadrupolar and magnetic interactions compete. We choose GdB₂C₂ to clarify the purely magnetic interaction in this system because the Gd ion has no quadropolar moment. We obtained diffraction data using reflection geometry and concluded that the magnetic interaction is antiferromagnetic in the c plane and ferromagnetic along the c axis.
