几种新型 CoNbB 非晶和微晶合金已被熔化淬火并测量了它们的磁矩。与 CoB、CoNb、CoV 和其他 CoNbB 合金中的钴矩抑制进行了比较。解决了两个问题：1）Nb 和 V（相同数量的价电子）抑制钴矩的不同速率；2）硼和铌共同抑制钴矩的综合效应。建议在第一种情况下可以通过 d-d 杂交来解释特征矩变化，在第二种情况下可以通过 p-d 和 d-d 杂交来解释。
Several new CoNbB amorphous and microcrystalline alloys have been melt quenched and their magnetic moments measured. Comparison is made with cobalt moment suppression in CoB, CoNb, CoV and other CoNbB alloys. Two issues are addressed: 1) the different rates at which Nb and V (same number of valence electrons) suppress the cobalt moment and 2) the combined effect of boron and niobium together in suppressing the cobalt moment. It is suggested that the characteristic moment variations can be accounted for by d-d hybridization in the first case and by p-d and d-d hybridization in the second case.
