2) electron spin relaxation
电子自旋弛豫
1.
It is found that spin relaxation lifetime of electrons lengthens with increasing excitation energy density for both samples, and the annealed (Ga,Mn)As has shorter carrier recombination and electron spin relaxation lifetimes as well as larger Kerr rotation angle than the as-grown (Ga,Mn).
运用飞秒时间分辨抽运-探测克尔光谱技术,研究了室温下退火及未退火(Ga,Mn)As的载流子自旋弛豫的激发能量密度依赖性,发现电子自旋弛豫时间随激发能量密度增加而增大,而在同一激发能量密度下,退火样品比未退火样品具有更短的载流子复合时间、电子自旋弛豫时间和更大的克尔转角,显示DP机理是室温下(Ga,Mn)As的电子自旋弛豫的主导机理。
3) electronic relaxation polarization
电子弛豫极化
4) electronic relaxation process
电子弛豫过程
1.
Effect of electronic relaxation process on air breakdown caused by repetition frequency HPM
电子弛豫过程对重复频率高功率微波大气击穿的影响
5) proton ralaxation
质子弛豫
1.
Methods The stability constants of gadolinium chelates were determined by using a compitition method and water proton ralaxation times T1 were measured by means of the inversion recovery method.
目的:探讨直链烷基修饰对Gd-DTPA稳定性和水质子弛豫性能的影响。
6) Resistivity relaxation
电阻弛豫

“质子-电子偶极-偶极”质子弛豫增强
物理学术语。原子核外层中不成对的电子质量小，但磁动性很强，可使局部磁场波动增强，促使氢质子弛豫加快，从而使T1和T2缩短，这种效应即为PEDDPRE。过渡元素和镧系元素大部分在d和f轨道有多个不成对电子，所以其离子往往具有PEDDPRE，可用来作顺磁性对比剂，如钆(Gd)。Gd在外层有7个不成对电子，具有很强的顺磁性。
