概要
- 論文の詳細を見る
Manganese metasilicate and manganese, ferrous and cobalt metager-manates with pyroxene structure were prepared by usual ceramic techniques. Ferrous and cobalt metasilicates were synthesized under high pressure. The magnetic susceptibilities of the eight pyroxenes were measured in the temperature range from 4.2 to 300゜K. All of these pyroxenes are antiferromagnetic at low temperatures. The Neel temperatures of MnSiO_3, MnGeO_3, CoSiO_3, and CoGeO_3 are respectively 7゜K, 10゜K, 50゜K and 41゜K. The susceptibility-temperature curves for FeSiO_3 and FeGeO_3 show two peaks. They are discussed on the basis of a simple molecular field approximation.
