Abstract

The Y(CoXAl1-X)3 system crystallizes in BaPb3-type structure for x ≤ 0.4 and PuNi3-type for x ≥ 0.6. The magnetic measurements were performed in temperature range, 4.2-800 K and external magnetic fields up to 10 T. The compounds with x ≥ 0.6 are ferromagneticaly ordered. For x ≤ 0.4 no magnetic order, down to 4.2 K is shown. For all compositions, the thermal variations of magnetic susceptibilities obey Curie-Weiss type dependencies. Cobalt magnetic behaviour is analyzed in spin fluctuation model..
