Abstract
The saturationmagnetization of gallium‐substituted yttriumirongarnetsingle crystals of composition Y3[Fe2−x Ga x ](Fe3−y Ga y ) O12 with 0≤x+y≤1.5 has been investigated in the temperature range 4.2≤T≤Tc . The magnetization values are below most data of previous investigations on this system. From the fit of the molecular field theory to the experimental results at T=4.2 K the fraction of the tetrahedral gallium ions ft =y/(x+y) could be deduced and are found to range between 1 and 0.91 for 0≤x+y≤1.5. The compensation temperature occurring for x+y>1 has been studied as a function of the gallium distribution.This publication has 25 references indexed in Scilit:
