Novel material with ferroelectricity and ferromagnetism may lead to better memory

Portions of the BiFeO3 lattice of cycloidal and collinear phases with only Fe ions are shown at left and right, respectively. The arrows indicate the Fe3+ moment direction. The ground state of BiFeO3 had a cycloidal spin structure, which is destabilized by substitution of Co for Fe and at higher temperatures. The spin magnetic moments compensate with each other in the left panel, but canting between neighboring spins leads to the appearance of weak ferromagnetism in the left panel.

Scientists at Tokyo Institute of Technology (Tokyo Tech) have demonstrated that ferroelectricity and ferromagnetism coexist at room temperature in thin films of bismuth-iron-cobalt oxide. The research could have implications in the next generation of computer memory and sensors. Traditional computer

Safety vs. performance

The creepage distance is the shortest path between two conductors along the surface of an isolator (typically a PCB)

When designing a switch-mode power supply (SMPS) operating losses and the ability to dissipate heat are critical selection criteria for MOSFETs. The standard TO-220 package is generally good at dissipating heat and the wide range of heatsinks and forced-air cooling options available can easily improve this.
