Water flow tracks earthquake healing

Comparison of an anapole field with common electric and magnetic dipoles. The anapole field, top, is generated by a toroidal electrical current. As a result, the field is confined within the torus, instead of spreading out like the fields generated by conventional electric and magnetic dipoles. (Michael Smeltzer / Vanderbilt)

Magnetic structure in a colossal magneto-resistive manganite is switched from antiferromagnetic to ferromagnetic ordering during about 100 femtosecond (10^-15 s) laser pulse photo-excitation. With time so short and the laser pulses still interacting with magnetic moments, the magnetic switching is driven quantum mechanically– not thermally. This potentially opens the door to terahertz (10^12 hertz) and faster memory writing/reading speeds.(credit: DOE Ames Laboratory)
