研究了强增强泡利顺磁LaCo9Si4和弱铁磁YCo9Si4之间固溶体Y1 − xLaxCo9Si4的磁性.铁磁区的居里温度TC和顺磁区的变磁转变场H M随x连续变化，当x ≥ 0.15时，居里温度趋近于零，表明存在一个由自发铁磁性转变为场致铁磁性的临界点.
The magnetism of solid solution Yi 1− x La x Co 9 Si 4 between strongly enhanced Pauli paramagnetic LaCo 9 Si 4 and weakly ferromagnetic YCo 9 Si 4 has been investigated. The Curie temperature T C in the ferromagnetic region and the metamagnetic transition field H M in the paramagnetic region change continuously against x and approach zero at the same composition x≊ 0.15, suggesting the presence of a critical point from spontaneous to field-induced ferromagnetism.
