Emergence of ferromagnetism at the onset of moiré Kondo breakdown Kondo physics has been observed in moiré bilayers, but the expected magnetic transitions have not been reported. Now, a metal–insulator tran

Physicists know their hard-won understanding of nature’s laws is incomplete. They don’t know why certain particles have mass, what sort of invisible stuff seems to be holding galaxies together, or what sort of energy is driving the universe’s expansion. But their biggest blind spot is one...
Both E and B are force fields, which extend throughout a volume of space. But they exert distinct and different forces. The electric field E exerts a force on a charge q in the direction of the field vector. The magnetic field B exerts a force on moving charges or current-carrying wir...
Environment The aggregate of all external and internal conditions (such as temperature, humidiy, radiation, magnetic and electric fields, shock vibration, etc.) either natural or man made, or self-induced, that influences the form, performance, reliability or survival of an item. Environmental stre...
Describe the phenomenon of capacitance and the effects of dielectrics.4. Explain the relationship between current and resistance and apply these concepts in the analysisofdirect current circuits.5. Explain the nature and sources of magnetic fields and how to calculate them from simple current...
A solenoid is used to generate a magnetic field. The solenoid has an inner radius a, length , and N total turns of wire. A power supply, not shown, is connected to the solenoid and generates current I, as shown in the figure on the left above. The x-axis runs along the axis ...
Magnetic Materials Perovskites Spintronics Introduction The common thread linking the family of high-temperature superconductors is that competing interactions involving charge, spin, lattice, and orbital degrees of freedom conspire with electronic correlation effects to produce many complex properties in this ...
Solar flares significantly impact the conditions of the Earth’s ionosphere. In particular, the sudden increase in X-ray flux during a flare penetrates down to the lowest-lying D-region and dominates ionization at these altitudes ( – 100 km). Measurements of very low frequency (VLF: 3...
