Recent progress in organic spintronics is given an informative overview, covering spin injection, detection, and trans-port in organic spin valve devices, and the magnetic field effect in organic semiconductors (OSCs). In particular, we focus on our own recent work in spin injection and the organic magnetic field effect (OMFE).  相似文献

反相高效液相色谱法测定玉米中玉米赤霉烯酮   总被引:5,自引:0,他引:5  
建立了反相高效液相色谱法检测玉米中玉米赤霉烯酮的分析方法.该方法的标准曲线回归方程为y=2.97×103 5.23×104ρ(r=0.9998);玉米样品3个水平的加标回收率分别为84.8%,86.7%和89.2%;相对标准偏差分别为4.0%,5.2%和4.4%;加标浓度为50 ng/g的玉米样品日内相对标准偏差为0.69%;玉米样品日间相对标准偏差为2.6%;方法检出限为3.0 ng/g.  相似文献

For the organic magnetoresistance(OMAR) effect, we suggest a spin-related hopping of carriers(polarons) based on Marcus theory. The mobility of polarons is calculated with the master equation(ME) and then the magnetoresistance(MR)is obtained. The theoretical results are consistent with the experimental observation. Especially, the sign inversion of the MR under different driving bias voltages found in the experiment is predicted. Besides, the effects of molecule disorder,hyperfine interaction(HFI), polaron localization, and temperature on the MR are investigated.  相似文献
