Enhanced Perpendicular Magnetic Anisotropy of Co-Rich Type Co–Pt Film by Inserting Pt Underlayer

IEEE Transactions on Magnetics (2015)

Ting-Hsuan You Yu-Shen Chen Yin-Cheng Ju Yu-Ting Lin Hsi‐Chuan Lu

The Co-rich type Co-Pt alloy thin films were deposited on various thicknesses of Pt underlayer (tPt) on glass substrates at room temperature. It was observed that the magnetic properties, microstructures, and phase structures of Co-Pt films were significantly affected by Pt(111) underlayer. At t _Pt = 5 nm, very small Pt grains induced multiple orientations in Co-Pt films, and then showed the longitudinal magnetic anisotropy (LMA). At t _Pt = 10 nm, columnar Co-Pt grains with hcp(002) orientation grew on a single Pt(111) grain, leading c-axis to be normal to the plane. The perpendicular magnetic anisotropy (PMA) of the film was enhanced. Further increase the tPt above 20 nm, Co-Pt grains exhibited hcp(100) orientation and the LMA is dominated again. In this paper, strong relationship between microstructures and magnetic properties in Co-Pt/Pt bilayer films was observed. The enhanced PMA in the Co-Pt/Pt bilayer film at t _Pt = 10 nm is due to the existence of the column-like structure and strong hcp(002) orientations.

Electrical and Magnetic Properties of Multiferroic $(1\hbox{-}{\rm x})\ {\hbox{BiFeO}}_{3}\hbox{-}{\rm x}\ {\hbox{CoFe}}_{2}{\hbox{O}}_{4}$ Nanocomposite Thin Films Derived by Sol-gel Process

IEEE Transactions on Magnetics (2014)

Mintu Tyagi Mukesh Kumari Ratnamala Chatterjee An‐Cheng Sun Puneet Sharma

In the present work, multiferroic (1-x) BiFeO ₃ -x (CoFe ₂ O ₄ ) ( x=0, 0.3, 0.5) nanocomposite thin films were prepared by sol-gel spin coating process. Structural, electrical and magnetic properties of nanocomposite thin films have been studied. X-ray diffraction study confirmed the co-existence of both perovskite BiFeO ₃ (BFO) and spinel CoFe ₂ O ₄ (CFO) phases. Atomic force microscopy shows CFO particles distributed in BFO matrix. These nanocomposite thin films exhibit both ferroelectric and ferromagnetic switching at room temperature. The magnetic and dielectric properties are improved by incorporation of CFO grains in matrix of BFO. The saturation magnetization (M _s ) increases as x varies from 0 to 0.5. For x=0.5, M _s is found as high as ~ 196 emu/cm ³ . Coercivity is increased with CFO concentration and found maximum ( H _c ~ 1.20 kOe) for x=0.50. This large increase in coercivity indicates strong magnetoelastic coupling. The dielectric constant of the films is increased from 240 (for x=0) to 370 (for x=0.5). All composite films show ferroelectric behavior, however the ferroelectric properties are found to decrease with incorporation of magnetic phase.

Hearing assessment in mobile phone users

International Journal of Community Medicine and Public Health (2023)

Dimple Sahni Parvinder Singh Puneet Sharma Amandeep Kaur Priya Sahni

Background: Mobile phones have become an indispensable part of today's modern world. But with various day-to-day benefits, mobile phones also bring detrimental effects on the health of users. Ear being the closest organ in contact with phones, faces maximum effect of electromagnetic waves generated by them. Chronic exposure to these waves and sounds can result in permanent hearing loss. Hence, the present study was done to assess the association between hearing loss and duration of mobile usage. Methods: This cross-sectional study was conducted on mobile phone users between the age group of 20 and 40 years in the Department of ENT, Rajindra Hospital, Patiala over 6 months (1 August 2022 to 31 January 2023). 600 volunteers were involved and divided into three groups based on the duration of mobile phone usage. Pure tone audiometry and DPOAE were used to assess the hearing loss in these subjects. Results: A variable degree of hearing loss was observed on PTA and DPOAE in all three groups with a significant association between hearing loss and the duration of mobile phone usage. A higher proportion of sensorineural hearing loss was observed in the group with mobile phone usage of more than 1 hour per day for a minimum of 4 years as compared to those who used them for <1 hour per day for a minimum of 4 years and control group (p=0.001) which was significant statistically. Conclusions: People using mobile phones for long hours are at higher risk of developing hearing loss, especially in the dominant ear.

Lens Aberration Aware Timing-Driven Placement

Andrew B. Kahng Chul‐Hong Park Puneet Sharma Qinke Wang

Process variations due to lens aberrations are to a large extent systematic, and can be modeled for purposes of analyses and optimizations in the design phase. Traditionally, variations induced by lens aberrations have been considered random due to their small extent. However, as process margins reduce, and as improvements in reticle enhancement techniques control variations due to other sources with increased efficacy, lens aberration-induced variations gain importance. For example, our experiments indicate that lens aberration can result in upto 8% variation in cell delay. In this paper, we propose an aberration-aware timing-driven analytical placement approach that accounts for aberration-induced variations during placement. Our approach minimizes the design's cycle time and prevents hold-time violations under systematic aberration-induced variations. On average, the proposed placement technique reduces cycle time by∼5% at the cost of∼2% increase in wirelength.
