III-V 화합물 자성 반도체의 강자성체 천이온도에 관한 연구
Ferromagnic Transitition Temperature of Diluted Magnetic III-V Based Semiconductor
초록
Ferromagnetism in manganese compound semiconductors open prospects for tailoring magnetic and spin-related phenomena in semiconductors with a precision specific to III-V compounds. Also it addresses a question about the origin of the magnetic interactions that lead to a Curie temperature(Tc) as high as 110 K for a manganese concentration of just 5%. Zener's model of ferromagnetism, originally suggested for transition metals in 1950, can explain Tc of
