A comparison of ZnO films deposited on indium tin oxide and soda lime glass under identical conditions
ZnO films have been grown via a vapour phase transport (VPT) on soda lime glass (SLG) and indium-tin oxide (ITO) coated glass. ZnO film on ITO had traces of Zn and C which gives them a dark appearance while that appears yellowish-white on SLG. X-ray photoelectron spectroscopy studies confirm the traces of C in the form of C–O. The photoluminescence studies reveal a prominent green luminescence band for ZnO film on ITO

Study of Local Non-reflective Boundary Condition on Soil Domain
AbstractThis paper presents a computational (finite element analysis) study for numerically simulating the elastic wave propagation problem in a two-dimensional homogeneous half space. The theoretical formulations of development and implementation of local non-reflecting boundary condition (NRBC) at the soil truncated boundaries has been discussed in detail. A dynamic analysis of the elastic soil domain using time marching scheme has been carried out and comparative studies of the responses from different boundary conditions at the truncated boundaries also has been provided to get the physical idea of the wave reflection phenomena and its absorption capability using NRBCs. The results justify the utility of implementing the local types of NRBC's on the truncated boundaries of the soil domain for solving coupled dynamic problems
Solitary fibrous tumor of the orbit presenting in pregnancy
A 32-year-old woman, three months pregnant, reported with the complaint of protrusion of the right eye for six months. She gave history of rapid protrusion of eyeball for the last two months along with the history of double vision for the last one month. Computer tomography (CT) scan revealed a well-defined mass lesion in the intraconal space of the right orbit which was excised through a lateral orbitotomy approach. Histological examination and immunohistochemistry revealed a solitary fibrous tumor, which showed a rapid progression in pregnancy

Electric field induced parametric excitation of exchange magnons in a CoFeB/MgO junction
Inspired by the success of field-effect transistors in electronics, electric field controlled magnetization dynamics has emerged as an important integrant in low-power spintronic devices. Here, we demonstrate electric field induced parametric excitation for CoFeB/MgO junctions by using interfacial in-plane magnetic anisotropy (IMA). When the IMA and the external magnetic field are parallel to each other, magnons are efficiently excited by electric field induced parametric resonance. The corresponding wavelengths are estimated to be tuned down to exchange interaction length scales by changing the input power and frequency of the applied voltage. A generalized phenomenological model is developed to explain the underlying role of the electric field torque. Electric field control of IMA is shown to be the origin for excitation of both uniform and parametric resonance modes in the in-plane magnetized sample, a crucial element for purely electric field induced magnetization dynamics. Electric field excitation of exchange magnons, with no Joule heating, offers a good opportunity for developing nanoscale magnonic devices and exploring various nonlinear dynamics in nanomagnetic systems
Simulations on the Effect of Magnetic Anisotropy on Switching of an Easy Cone Magnetized Free Layer
The easy cone state of magnetization that arises as a result of a competition between the second- and fourth-order perpendicular magnetic anisotropies has the advantage of a non-zero electric-field torque without the application of a bias magnetic field and is thus a potential candidate for purely voltage-driven magnetic storage devices. In this article, the onset of the easy cone state of magnetization is simulated in a ferromagnet film. Subsequently, the switching field and time for voltage-controlled magnetization switching process are studied as a function of the inclination angle of the easy cone state from the film normal in the range of 0°- 45°. The switching field is found to decrease with decreasing anisotropy. The switching time is found to become faster for higher inclination angle of the easy cone state due to an increase in its torque
