“…Later, [24][25][26] this superconducting behavior was ascribed to be from an additional phase containing carbon. On the other hand, YCo 4 B is a ferromagnetic material with T c ¼ 380 K, exhibiting spin reorientation at 150 K due to the competition among the two crystallographic sites of Co. 12 The magnetic properties of the RNi 4-x Co x B compounds were studied in materials with Sm, 27 Pr, 22 Nd, 28 and La. 29 For these, the increasing of Co content increases monotonically the saturation magnetization (M s ) and Curie temperature (T c ).…”

The magnetic anisotropy of 3d sub-lattices has an important rule on the overall magnetic properties of hard magnets. Intermetallics alloys with boron (R-Co/Ni-B, for instance) belong to those hard magnets family and are useful objects to help to understand the magnetic behavior of 3d sub-lattice, specially when the rare earth ions R do not have magnetic nature, like YCo 4 B ferromagnetic material. Interestingly, YNi 4 B is a paramagnetic material and Ni ions do not contribute to the magnetic anisotropy. We focused therefore our attention to YNi 4-x Co x B series, with x ¼ 0, 1, 2, 3, and 4. The magnetic anisotropy of these compounds is deeper described using statistical and preferential models of Co occupation among the possible Wyckoff positions into the CeCo 4 B type hexagonal structure. We found that the preferential model is the most suitable to explain the magnetization experimental data. V
