Abstract
The magnetization, a.c. susceptibility, resistivity and magnetoresistance have been measured for the invariable-unit-cell-parameter compounds. The Si substitution for Co in yields a dramatic initial increase of , whereas the 3d magnetic moment is reduced. These findings may be attributed to the strong involvement of Si p states in the hierarchy of exchange interactions. The magnetic phase transition at is of first order for the compounds with x < 0.075. For these compounds, the coexistence of metamagnetism and the quenching of spin fluctuations at are provided.Keywords
