The phenomenon of magnetism is one of the key components of today's technological progress. Magnetic interactions and magnetic materials are essential for the scientific disciplines of physics, chemistry and biology, making this subject truly multidiscipli ...
The problem of large-scale molecular dynamics simulations of iron has recently attracted attention in connection with the need to understand the microscopic picture of radiation damage in ferritic steels. In this paper we review the development of a new in ...
Magnetic anomalies observed by the Mars Global Surveyor mission are attributed to crustal remanence. SNC (Shergotty-Nakhla-Chassigny) meteorites are likely samples of the Martian crust and are amenable to mineralogical and magnetic measurements essential t ...
We report the preparation and magnetic properties of Co2FeO4nanowires grown by electrodeposition inside the pores of anodic aluminum oxide (AAO). The synthesis requires two successive steps: the electrodeposition of fairly amorphous Fe-Co oxides or hydroxi ...
We study from first principles the magnetism in graphene induced by single carbon atom defects. For two types of defects considered in our study, the hydrogen chemisorption defect and the vacancy defect, the magnetism due to the defect-induced extended sta ...
Using a generalized anisotropic tokamak equilibrium and an exact guiding centre drift formulation, the effect of parallel and perpendicular anisotropy on the toroidal precession drift is investigated. Significant differences between parallel and perpendicul ...
Predicted by the theory, ferromagnetism is expected in Co-doped ZnO. Recently, ferromagnetism above room temperature was reported in thin films as well as in bulk samples made of cobalt-doped zinc oxide. In this study, we report the preparation of ZnO dope ...
Bulk magnetism in solids is fundamentally quantum mechanical in nature. Yet in many situations, including our everyday encounters with magnetic materials, quantum effects are masked, and it often suffices to think of magnetism in terms of the interaction b ...
A technology for the fabrication of bismuth Hall sensors integrated on SU-8 cantilevers has been developed in this project. Hall sensors with active area of 2 x 2 μm2 (Fig.2) are produced with lift-off and resized to 200 x 200 nm2 (Fig.3) with the FIB. SU- ...
