Electric-field and magnetic-field effects on electronic tunneling through magnetic-barrier nanostructures[J] . Maowang Lu,Zhenhong Dai,Lide Zhang,Xiaohong Yan.The European Physical Journal B . 2003 (3)Mao-Wang L
Using the ferromagnetic metal SrRuOas a model system, we demonstrate an efficient and reversible control of both structural and electronic phase transformations through the electric-field controlled proton evolution with ionic liquid gating. The insertion of protons results in a large structural expansion...
关键处为“represented in ___ manner ___ an electric field”。选项分析:1. **A. such … as**: “such...as”需搭配单数可数名词时,通常需添加冠词(如“such a manner as”)。但题目中空缺处仅有“manner”,无冠词,语法不完整,因此排除。2. **B. the same … as**: “the same...as”...
1.2.1.1 Coupling to Static Magnetic Fields People are generally unaffected by static magnetic fields, unless they move around these fields. The magnetic field will thus exert a physical force on electrically charged particles moving through the field. Therefore, movement with respect to magnetic field...
If the electric field is switched off, and the same magnetic field is maintained then the electrons move: View Solution The mass of an electron is m, its charge is e and it is accelerated from rest through a potential difference, V. The velocity of electron can be calculated by formula:...
Manipulating a quantum state via electrostatic gating has been of great importance for many model systems in nanoelectronics. Until now, however, controlling the electron spins or, more specifically, the magnetism of a system by electric-field tuning has proven challenging1,2,3,4. Recently, atomica...
Those equations state that: (1) an electric field is generated by the electric charges; (2) a flowing current or alternating electric field can generate the magnetic field; (3) the magnetic field has no source; (4) an alternating magnetic field can create an electric field through induction...

of a charged conducting sphere through a uniform electric field, in a direction parallel to the electric force of the field, and has calculated the increase in the magnetic energy and inertia of the sphere resulting from the re-distribution of the charge under the influence of the field. His...
Fig. 1: Schematic of the experimental realization of dynamical multiferroicity. a, SrTiO3 unit cell in the absence of a terahertz electric field. When a circularly polarized terahertz field pulse drives a circular atomic motion, dynamical multiferroicity is expected to create a net magnetic moment ...
