Sažetak
We report on ac susceptibility study of the CePt Kondo ferromagnet together with its derived alloy systems $Ce_{;x};La_{;1-x};Pt$ and $Ce_{;x};Y_{;1-x};Pt$. We show that these transitions display some characteristics of frustrated spin glass systems rather then pure ferromagnetic ones. Namely, the transitions are frequency dependent. Also, we notice some thermal cycling effects. In $Ce_{;x};La_{;1-x};Pt$, the transition temperature decreases with decreasing {;x};. In the $Ce_{;x};Y_{;1-x};Pt$ alloy system appear two peaks in the ac susceptibility data. Interestingly enough, both peaks are at higher temperatures than one expects from the Kondo picture. It comes out as the transition temperature does not depend on the strength of the magnetic moment of the Ce ion.
