Ultrathin metal-free g-C3N4 nanosheets with intrinsic room temperature ferromagnetism were synthesized by heating urea in an airtight container at different temperatures. Results indicate that the samples' saturation magnetization increases with the carbon defect concentration, revealing its carbon defect related ferromagnetism. Moreover, we further confirmed the defect induced ferromagnetic na...

Introduction: Induction heating is the release of thermal energy within a body due to the resistance of that material to a current passing through it. This mechanism is also called Joule heating or Ohmic dissipation. Induction heating has been proposed as a process that could have caused metamorphism and melting in planetesimals in the early solar system [1]. Although other theories are more wi...

The paper deals with the traveling wave cylindrical heating systems. analysis presented is analytical and a multi-layer model using geometry used to obtain theoretical results. To validate results, practical constructed, tested results are compared ones. Comparison showed that adopted method efficient in describing performance of such induction

Structural phase transformations in the ferromagnetic FeNi alloys is discussed on the basis of first-principles and molecular-dynamics simulations. In the molecular-dynamics study effective potentials have been used which were derived by the Embedding Atom Method. The simulations reproduce fairly well the austenitic transformation upon heating, while for the martensitic transformation upon cool...

Using 100 fs laser pulses, a high-frequency exchange and a low-frequency ferromagnetic resonance mode have been excited and detected in an amorphous Gd(1-x)Co(x) (78≤x≤85) ferrimagnetic thin film, on both sides of its angular momentum compensation composition. The excitation efficiency of these modes strongly depends on the amount of laser-induced heating. Ways of selectively and efficiently ex...
