Multiferroic meta-magnetic shape memory alloys are well known for exhibiting large magnetic field induced actuation strains, giant magnetocaloric effects, magneto-resistance, and structural and magnetic glassy behaviors. Thus, they are candidates for improving modern day sensing, actuation, magneto-resistance, and solid-state refrigeration processes. Until now, however, experimental apparatuses...

Carbon nanotubes (CNT) belong to the most promising new materials which can in the near future revolutionize the conventional electronics. When sandwiched between ferromagnetic electrodes, the CNT behaves like a spacer in conventional spin-valves, leading quite often to a considerable giant magneto-resistance effect (GMR). This paper is devoted to reviewing some topics related to electron corre...

This work presents a first approach in high fidelity current measurement using GMR (giant magneto resistance) sensors combined along with an air coil to obtain a wide bandwidth current probe. The proposed probe is a prototype of a clamping version capable to capture currents of +/400 amperes from DC up to 10 MHz. This paper presents an argument for this equipment as well as the implementation o...

Large changes in the electrical resistance induced by the application of a small magnetic field are potentially useful for device-applications. Such Giant Magneto-Resistance (GMR) effects also provide new insights into the physical phenomena involved in the associated electronic transport. This study examines a "bell-shape" negative GMR that grows in magnitude with decreasing temperatures in mm...

In our electronic world, since the discovery of electron by J J Thomson in 1897, scientists have been working strenuously to build the Digital World that we enjoy today. To satisfy a common man‘s need, researchers have been scratching the very basis of electronics – ̳Electron‘. All that we are using today is the flow of a bundle of electrons to determine the electronic outcome instead of the ba...

Silicon has persevered as the primary substrate of microelectronics during last decades. During last years, it has been gradually embracing the integration of ferroelectricity and ferromagnetism. The successful incorporation of these two functionalities to silicon has delivered the desired non-volatility via charge-effects and giant magneto-resistance. On the other hand, there has been a numero...

We discuss the possibility that gaseous giant planets drive strong outflows during early phases of their formation. We consider the range of parameters appropriate for magneto-centrifugally driven stellar and disk outflow models and find that if the proto-Jovian planet or accretion disk had a magnetic field of ∼> 10 Gauss and moderate mass inflow accretion rates through the disk of less than ∼ ...
