Magnetisation control by heat

ID: F1601-06

A laser-induced pulse of temperature could allow the control of the magnetisation in the nanoscale recording news of hard drives. This astonishing effect could lead to much denser magnetic memories, providing an unprecedented scale of capacity development. Over the last many years, the magnetic disk storage space thickness – the number of bits of information stored per unit area – doubles around every 18 months. This trend is expected to carry on, showing the fast rate of technical progress in this area. However, larger storage space capacities must go hand in hand with the ability to read and write bits at smaller size scales. The next generation of disk read-and-write heads will utilize temperature to record information and shop data assisted by nanoscale antennas energised by semiconductor lasers that operate at high temperatures. Against this backdrop, a task is developing asers that can be integrated with magnetic recording technology and creating antennae to supply and focus the power on a range of a couple of tens of nanometres that causes the material to be heated. This heat-assisted magnetic recording (HAMR) approach will enable storage space densities of 1 terabit per square inch and beyond. So far, researchers have actually created innovative semiconductor lasers utilizing etching techniques to incorporate the laser mirror on a chip. Optimising the pattern transfer procedure ensures the smoothness of the mirror, ensuing in products with comparable performance to those perhaps not incorporated on a circuit. Venture work has also been geared to investigating unique methods for mirror protection with a focus on atomic layer deposition. The first reliability tests are underway. The laser wafer that comprises numerous layers of materials with varying optical and electric properties features been modelled using device simulators. The layer compositions and depth are optimised for high-temperature operation through detailed simulations. Based on these designs, scientists have effectively prepared and characterised a new laser structure that demonstrated excellent overall performance in terms of production power at high operating conditions. This breakthrough technology revolutionises data storage by further pushing current capacity limits permitting the scaling of data storage in the ‘cloud’. Improvements in the storage technology should assist advance all kinds of information administration.

    Paper to conquer new markets

    ID: F1512-07

    A new project adopted a multidisciplinary approach, bringing together 12 research and industry lovers with various backgrounds, including materials science and engineering, chemistry, physics, electronic devices, and micro- and nanotechnologies. They envisioned paper items such as labels with particular autonomous properties that interact with users and/or report modifications in their environment. Work centred on developing new types of paper, fibres and inks on a commercial scale, as well as on new printable useful elements such as sensors, displays, memory modules and batteries. It's also developing a novel manufacturing process and printing technology, eventually resulting in large-area hybrid organic/inorganic papers with improved performance and expense effectiveness. After developing security labels, the group tested three reference papers for printability in relation to useful and peripheral elements. Hybrid circuits had been created by the group, with assessment showing both publishing and electrical integration performance. Industrial printing test runs were realised at a factory to move results of the work on the demonstrators, and an aesthetic assessment system had been installed and tested at the same center. Undertaking efforts pave the way for a renewal of the paper industry's products with more additional value functional products. Outcomes open up new options for paper and publishing industries in the growing market of low-cost and large value added printed electronics. The technology also features prospective for application in sectors related to general public safety (monitoring air poisoning and pollution), packaging (food quality during storage and transport), and chemical substances production and make use of.
