The Tb{sub 1{minus}x}Y{sub x}Fe{sub 11}Ti (x= 0, 0.2, 0,4, 0.6 and 0.8) compounds have been studied in magnetization and ac-susceptibility measurements as a function of temperature. The results show that the Tb{sub 1{minus}x}Y{sub x}Fe{sub 11}Ti compounds with x = 0, 0.2 and 0.4 undergo a spin reorientation of the axis-to-plane type (referred to decreasing temperature), while the samples with x = 0.6 and 0.8 remain easy-axis compounds down to the lowest temperature measured (4.2 K). The spin-reorientation temperature, T{sub sr} is found to decrease with increasing Y content. The observed temperature dependence or the magnetic structure of this series of compounds has been analyzed on the basis of a crystal-field model with the following set of crystal-field parameters: B{sub 2}{sup 0} = 0.45 K, B{sub 4}{sup 0} = {minus}1.8 {times} 10{sup {minus}4} K and B{sub 6}{sup 0} = 0 K.
