摘要：
The specific magnetization and magnetic susceptibility of ferrogarnets of the composition Y3-xCex(Fe0.5Ga0.5)(5)O-12 (x = 0; 0.5) obtained by the gel combustion method have been measured. It has been found that after synthesis and subsequent crystallization at pressure approximate to 10(-2) Pa at 1023 K for 2 h, the temperature of magnetic phase transformation in the studied compositions Y3-xCex(Fe0.5Ga0.5)(5)O-12 increases with the replacement of yttrium ions Y3+ by Ce3+. In this case, the effective Curie-Weiss temperature theta(eff) of the antiferromagnetic component of exchange magnetic interactions in Y2.5Ce0.5Fe2.5Ga0.5O12 varies from vertical bar-570 vertical bar to vertical bar-650 vertical bar K.
