They are caused by the coexistence in the crystal of spontaneous ferroelectric and magnetic moments 通常将这类具有线性磁电效应的物质称为磁电体。
If all the shells containing electrons are completely filled , the effects cancel out and each atom has a resultant zero magnetic moment 如果有的电子层上均排满电子,则作用力互相抵消,而导致每个电子的磁矩为零。
The expression of magnetic moment of an electrified body is similar to that of moment of inertia of a body with various density 摘要带电体定轴转动的磁矩计算与刚体定轴转动的转动惯量相仿，平行轴定理有助于磁矩计算。
The magnetic moments per cr atom vary significantly with cr concentration , and the trend of variation is in agreement with that of the experiment 计算结果表明cr原子的磁矩随掺杂浓度有明显的变化,变化趋势和实验吻合。
The coupling between cr atoms in the system with two cr atoms considered is found to be ferromagnetic , and the magnetic moment per cr atom is similar to the case in which only one cr atom is considered in the same doping concentration 在包含两个cr原子的体系中cr原子之间是铁磁性偶合,每个cr原子的磁矩与相同浓度下掺杂一个cr原子的磁矩相近。
It must then make fewer turns per second , in obedience to a law of physics called the conservation of magnetic moment ( this is similar to the law of conservation of angular momentum that slows a spinning ice dancer down as he spreads his arms ) 服从称为磁矩守恒的物理定律，其会减少每秒旋转的次数（这一定律与角动量守恒定律很相似，花样滑冰舞者通过伸展自己的上肢来减慢自己旋转的速度就是利用这一原理） 。
We consider a neutral particle with magnetic moment antiparallel to the field . with the interaction potential energy between the magnetic moment of the particle and the magnetic field , we obtain the classical motion equation of the neutral particles in the loffe trap . in some limit conditions , by using the perturbative method , the equations may take on concise forms . of which the two equations about x and y are mathieu equations . if we properly set the parameters and have the condition a > > q > 0 , we can solve the mathieu equation with the traditional wkbj method . as a new attemptation , with fourier series expansion we solve the mathieu equation and obtain the classical motion law of the neutral particles 若阱的参数设置使得条件> > q 0成立时，我们可以利用传统的wkbj方法近似求解马丢方程。作为一种新的尝试，本文还采用傅立叶级数展开的办法来对马丢方程进行求解，从而得到中性粒子在阱中的经典运动规律。在研究ioffe阱对中性粒子的囚禁问题时，实际上我们更感兴趣的是马丢方程的周期解，而要想获得这种周期解，和q必须满足一定的关系，亦即必须选择阱的特定的参数和粒子的特定初始条件，对这一问题我们进行了尝试性的研究。
The results showed that the microstructure of as - deposited tbdyfe ii 1ms were amorphous and the crystal of tbfe2 were found in films after annealing at 500 . annealing films in vaccum could improve the saturation magnetization ms and the susceptibility , decrease the coercivity and the saturaion field , and make the direction of the magnetic moments parallel to the film plane 结果表明，制备态薄膜为非晶态结构，经过500真空退火热处理后，薄膜出现了tbfe _ 2的结晶物，薄膜的矫顽力和外场的饱和磁场大大降低，饱和磁化强度增强，初始磁化率提高，易磁化轴转向膜面。
