Magnetization in Phosphorus Doped Silicon

概要
- 論文の詳細を見る
Magnetization in phosphorus doped silicon was measured with magnetic fields up to 95 kG and temperatures down to I . 5 K. The donor concentration of mea-sured samples ranged from O. 53 to 6.5 times 1018 cm ~ 3. The most heavily doped sample shows diamagnetic susceptibility which is consistent with a simplified pictuie of degenerate semiconductor. Other samples, including two metallic ones, show a temperature dependence of magnetization which can be attributed to free spins, and the number densities of free spins estimated from the magnetiza-tion curve are shown consistent with those estimated from the specific heat anomaly. The origin of these free spins is discussed with taking into account the intrastate Coulomb energy of localized states.
