转动一根裹有黏性流体(如蜂蜜)的杆,杆上可以保留部分液体不滴落.针对此现象,之前理论研究大多基于N-S方程求解,无法直观解释现象发生的物理机理.本文在理论上创新性地采用类似量纲分析的方法,通过受力分析,避免了复杂冗长的流体力学方程求解,得到了由重力、黏性力、离心力、表面张力共同作用、交互主导的简洁理论模型;实验上,通过搭建稳定装置及合理控制变量,得到自洽的实验数据.理论分析与实验结果吻合度高,直观解释了转动杆上黏性流体不滴落的物理本质与关键因素.

Enhancing the magnetoelectric coupling of Co4Nb2.9[100] by substituting Mg for Co

Frontiers of physics 2018年第5期13卷 73-78页

作者： Zhen Li Yi-Ming Cao Yin wang Ya Yang Mao-lin Xiang You-Shuang Yu Bao-Juan Kang Jin-Cang Zhang Shi-Xun Cao Department of physics International Center for Quantum and Molecular Structures and Materials Genome Institute Shanghai University Shanghai 200444 China Center for Magnetic Materials Devices Key Laboratory for Advanced Functional and Low Dimensional Materials of Yunnan Higher Education Institute Qujing Normal University Qujing 655011 China school of physics and {2. engineering Xinyang Normal University Xinyang 464000 China

We report experimental studies on enhancing the magnetoelectric （ME） coupling of Co4Nb2.9 by sub- stituting the non-magnetic metal Mg for Co. A series of single crystal Co4-xMgxNb2.9 （x = 0, 1, 2. 3） with a single-phase corundum-type structure are synthesized using the optical floating zone method, and the good quality and crystallographic orientations of the synthesized samples are confirmed by the Laue spots and sharp XRD peaks. Although the Neel temperatures （TN） of the Mg substituted crystals decrease slightly from 2. K for pure C04Nb2.9 to 19 K and 11 K for Co3MgNb2.9 and Co2.g2.b2.9, respectively, the ME coupling is doubly enhanced by Mg substitution when x = 1. The ME coefficient OlMg of Co3MgNb2.9 required for the magnetic field （electric field） control of electric polarization （magnetization） is measured to be 12.8 ps/m （13.7 ps/m）. These results indicate that the Mg substituted Co4-xMgxNb2.9 （x = 1） could serve as a potential candidate material for applications in future logic spintronics and logic devices.
