Diluted Magnetic Zn1-xMnxO Semiconductor Synthesized by Hydrothermal Method

摘要：

　　Diluted magnetic semiconductor Zn1-xMnxO crystals were synthesized at 430℃ for 24h by hydrothermal method.3mol·L-1KOH was used as the mineralizer,and the fill factor is 35%.The obtained crystals show a ZnO wurtzite structure,with positive polar faces0001,negative polar faces000(1),p faces(1)011 and-p faces (1) 01 (1) exposed.The height of the crystal is 5-30μ m and radius-height ratio is2∶1.Mn atom concentration of 2.6% (x=0.026) was determined using X-ray energy dispersive spectroscopy (EDS).The crystals show low-temperature ferromagnetism with Curie temperature of 50K.
