dc.description.abstractEn | The stannide CeZnSn was obtained in X-ray-pure form by induction-melting of the elements in a sealed tantalum ampoule. CeZnSn crystallizes with the YPtAs-type structure, space groupP63/mmc,a= 456.7(3),c= 1673.8(5) pm,wR2 = 0.0862, 259F2values, and 12 variables. The zinc and tin atoms build up puckered Zn3Sn3hexagons (Zn–Sn 271 pm) with weak interlayer Zn–Zn interactions(323 pm). Susceptibility measurements of CeZnSn reveal modified Curie-Weiss behavior above 50 Kwith an experimental magnetic moment of 2.77(1)μB/ Ce atom. The cerium magnetic moments order ferromagnetically atTC=5.2(1)K.119Sn Mössbauer spectra show a single tin site at an isomer shift ofδ= 1.967(4) mm/s subjected to a small quadrupole splitting of ∆EQ= 0.41(2) mm/s at 40 K. At 4.2 K a magnetic hyperfine field of 0.872(5) T is transferred to the tin site. From DFT scalar relativistic calculations of the electronic and magnetic structures, chemical bonding analysis reveals on one hand a weaker bonding of Zn than of Sn with the cerium substructures with a twice strongerCe1–Sn bond compared to Ce2–Sn. On the other hand, a ferromagnetic ground state is identified from total energy differences in agreement with experiment | |
