Structural and magnetic properties of the rare-earth–borocarbides, R5B2C6 (R=Y, Ce–Tm)

Solid state phase equilibria in the Gd–Si–B system at 1270K

“…Many studies have been devoted to the crystal chemistry and physical properties of ternary compounds comprising a rare earth, boron and carbon [1][2][3][4][5]. In addition, theoretical calculations have been performed in order to rationalize the nature of the chemical bond within the boron-carbon sublattice [6][7][8][9].…”

Crystal chemistry and physical properties of the ternary compounds RE5B4C5 (RE=Ce, Pr, Nd)

“…These prove that all RE 5 B 2 C 5 involving magnetic RE atoms undergo ferromagnetic transitions in the temperature region below 130 K. The heavy rare-earth metal (Tb-Tm) boride carbides exhibit a magnetic behaviour typical of narrow domain-wall ferromagnets [5]. The related series of compounds RE 5 B 2 C 6 (RE = Pr-Tm) also undergo ferromagnetic transitions, with the exception of Gd 5 B 2 C 6 , which is a meta-magnet (Néel temperature T N ~ 27 K) [6]. For La 5 B 2 C 6 the metallographic, analytical and structural investigations together with measurements of magnetic behaviour and specific heat clearly show that superconductivity is not an intrinsic property of this compound.…”
