Physics of polymorphic transitions in CeRuSn
Original language description
We report a detailed study of the polymorphic transitions in ternary stannide CeRuSn on high quality single crystals through a combination of x-ray diffraction experiments conducted at 300, 275, and 120 K, and measurements of the thermal expansion, magnetization, and resistivity, along main crystallographic axes. In addition, the transition was followed as a function of pressure up to 0.8 GPa. The present x-ray diffraction data show that the room temperature polymorph consists of the lattice doubled along the c axis with respect to the CeCoAl-type structure consistent with previous reports. Upon cooling, the compound undergoes two successive transitions, first to a quintuple (similar to 290 K) and than to a triple CeCoAl superstructure at similar to 225 K. The transitions are accompanied by a tremendous volume change due to a strong shrinking of the lattice along the c axis, which is clearly observed in thermal expansion. We advance arguments that the volume collapse originates from an
