Role of atomic vacancies and second-neighbor antiferromagnetic-exchange coupling in a ferromagnetic nanoparticle

Several factors may be responsible for disorder and frustration in a magnetic nanoparticle, including atomic vacancies on the surface and inside, impurity atoms, long-range magnetic exchange coupling, etc. We use Monte-Carlo simulations within the Heisenberg model to examine the role of randomly distributed atomic vacancies and long-range magnetic-exchange coupling on the temperature-dependent magnetic properties of ferromagnetic nanoparticles. In particular, we study the role of the second-neighbor antiferromagnetic exchange coupling and missing atoms inside the particle resulting in broken nearby bonds. We find that both factors may enhance the superparamagnetic behaviors of such particles.

A secure home automation prototype built on raspberry-pi

With the development of sensors, wireless mobile communication, embedded system, the technologies of the Internet of Things have been widely used in SmartMeter, public security, intelligent building and so on. Because of its huge market prospects, the Internet of Things has been paid close attention by several governments all over the world. IoT facilitates the seamless integration of wireless sensor networks. In this paper, we present an IoT prototype that is built on Raspberry Pi and uses SMTP (simple mail transfer protocol) for communication. Through this device, we have proposed a communication system that is less complex and more secure. It integrates with any "thing" and makes it electronically communicable. We give an implementation of the prototyping system and system validation.
