Relation between crystal structure and physical properties of Rn+1M5+3nB2n phases

Magnetic properties of the PrCo4−xNixB borides

“…Similar behavior has also been observed for the YCo 4 − x Ni x B compounds [17]. The saturation behavior with a small magnetization value indicates the presence of a weak ferromagnetic phase for x = 2.…”

“…for PrCo 4 B [15]. In the RT 4 B compounds with T = Co, Fe and Ni, the Co and Fe atoms are ferromagnetic [4,[14][15][16][17], while a small induced magnetic moment on the Ni sites was observed [11]. This study deals with the effect of the Ni substitution for Co on the crystal structure and the magnetic properties of the PrCo 4 − x Ni x B borides.…”

A high-energy inelastic neutron scattering investigation of the Gd–Co exchange interactions in GdCo4B: Comparison with density-functional calculations

“…23 A detailed investigation of isotype RCo 4 B phases has been undertaken by neutron diffraction and related results have been presented elsewhere. 26,24,37,38 This investigation shows that the two inequivalent Co sites carry significantly different magnetic moments. This result has been confirmed by electronic structure calculations.…”

“…4 B compounds have been the subject of several investigations. [34][35][36][37] GdCo 4 B is found to order below 503 K. The Gd and Co magnetic sublattices are coupled ferrimagnetically. At low temperatures, the Gd magnetization is dominant, whereas at high temperatures the Co sublattice magnetization is dominant.…”

Magnetic properties of the Pr1−xGdxCo4B compounds

“…The RCo 4 B phases, belonging to the R n+1 Co 3n+5 B 2n (n ¼ 0, 1, 2, 3, N) family of compounds with n ¼ 1, crystallize in the hexagonal (P6/mmm) CeCo 4 B-type structure which is obtained by an ordered substitution of boron for cobalt in every second layer of the CaCu 5 -type structure. In the CeCo 4 B-type structure, the R atoms occupy the 1a and 1b sites, the Co atoms are in the 2c and 6i sites, and the B atoms reside in the 2d sites [12,13]. As can be seen in Fig.…”
