3. The ferromagnet europium oxide has a Curie temperature of 70K. In this oxide, the europium ion has J : 2. Assuming the mean field model of 7 2 and g = ferromagnets, determine the ratio of the magnetization at 300 K in a field of 10-²1 to that at O K. Also calculate the internal magnetic field in europium oxide.
