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...
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...
The structure and dynamics of the solar corona is dominated by the magnetic field. In most areas in the corona magnetic forces are so dominant that all non
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 ...
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 ...
In LSW a laser pulse together with a static magnetic field produces axion and 27 the axion penetrates through an opaque wall thanks to the weak coupling with matter, and it then regenerates a photon via the coupling with the static magnetic field located over the wall. The solar axion ...
In metals, electrons are very mobile which allows a relatively easy flow of electrical current. However, at low temperatures, a magnetic field can shift electrons to a quantum state causing its resistance to change in an oscillating pattern. Insulators generally do not exhibit this effect. ...
