Abstract

The dependence of the magnetic properties of sintered materials of the composition (Pr1–z–xDyxGdz)12,55–12,81(Fe0,80Co0,20)balB5,71–6,25 (x = 0,34–0,58; z = 0,11–0,33)on the gadolinium concentration and sintering temperature of 1120–1140 °C was studied. The temperature coefficient of induction was measured in the temperature range of 20–100 °C. Demagnetization curves (magnetization and induction) were measured using a vibrating sample magnetometer (VSM) at temperature of 20±5 °C. The temperature dependences of the magnetization in the temperature range of 300–600 K were revealed. about the article states the effect of gadolinium on the magnetic characteristics of sintered materials.
