Ferromagnetic InMnAs on InAs Prepared by Ion Implantation and Pulsed Laser Annealing
摘要：
采用Mn离子注入和脉冲激光退火制备了铁磁InMnAs。InMnAs层在5 K时的饱和磁化强度为2.6 μ B/Mn，具有垂直磁各向异性.居里温度被确定为46 K，这是高于那些在以前的报告具有类似的Mn浓度。铁磁性进一步证明了大的磁性圆二色性。
英文摘要：
Ferromagnetic InMnAs has been prepared by Mn ion implantation and pulsed laser annealing. The InMnAs layer reveals a saturated magnetization of 2.6 mu_B/Mn at 5 K and a perpendicular magnetic anisotropy. The Curie temperature is determined to be 46 K, which is higher than those in previous reports with similar Mn concentrations. Ferromagnetism is further evidenced by the large magnetic circular dichroism.
