Abstract:
Tm4B3C4 crystallizes in the triclinic Gd4B3C4 structure type, space group P (1) over bar, a=3.4850(2), b=3.5220(2), c=11.6972(6), alpha=92.86(1), beta=96.43(1). gamma=90.14(1) according to X-ray powder diffraction. The magnetic properties of the compound Tm4B3C4 have been measured in the temperature range 2 K < T < 300 K and in various external fields up to B=7 T. The sample undergoes an anti-ferromagnetic transition at T-N = 3 K, and in fields B > 0.1 T a meta-magnetic transition is encountered. The measurements of the temperature dependence of the electrical resistivity proves a poor metallic state of this compound. (C) 2012 Elsevier Ltd. All rights reserved.
