    83 p.Recognised as the largest Asian tiger, South Korea remains one of the world's fastest growing economies since the 1960s. The Samsung Group is South Korea's largest chaebol. Samsung Futures Inc ("Samsung Futures") is a relatively newer addition to the family but has quickly become the industry leader in the derivatives market.Master of Business Administratio

    Thermal behavior of spin-current generation in PtxCu1-x devices characterized through spin-torque ferromagnetic resonance

    High temperature studies of spin Hall effect have often been neglected despite its profound significance in real-world devices. In this work, high temperature spin torque ferromagnetic resonance measurement was performed to evaluate the effects of temperature on the Gilbert damping and spin Hall efficiency of PtxCu1−x. When the temperature was varied from 300 K to 407 K, the Gilbert damping was relatively stable with a change of 4% at composition x = 66%. Alloying Pt and Cu improved the spin Hall efficiency of Pt75Cu25/Co/Ta by 29% to a value of 0.31 ± 0.03 at 407 K. However, the critical switching current density is dependent on the ratio between the Gilbert damping and spin Hall efficiency and the smallest value was observed when x = 47%. It was found that at this concentration, the spin transparency was at its highest at 0.85 ± 0.09 hence indicating the importance of interfacial transparency for energy efficient devices at elevated temperature.Agency for Science, Technology and Research (A*STAR)Economic Development Board (EDB)National Research Foundation (NRF)Published versionThe work was supported by the Singapore National Research Foundation, under a Competitive Research Programme (Non-volatile Magnetic Logic and Memory Integrated Circuit Devices, NRF-CRP9-2011-01), and an Industry-IHL Partnership Program (NRF2015-IIP001-001).

    Abstract. This paper provides a brief description of Robo-Erectus (RE), the humanoid developed in the Advanced Robotics and Intelligent Control Centre of Singapore Polytechnic that will participate in the humanoid league of RoboCup 2005. The project to develop a low-cost humanoid platform is presented. The mechanical structure of Robo-Erectus and the evolution of its various models is presented. The development of its control systems and the planning of itsdynamically stable walking and kicking gait of the robot is also described.
