Specifically, the team found that the angrites» remnant magnetization could have been produced by an extremely weak magnetic field of no more than 0.6 microteslas, 4.563 billion years ago, or, about 4 million years after the start of the solar system.
In the experiment researchers discovered an unexpected effect: when magnetization directions in two ferromagnetic layers were not parallel, the interaction between these layers and superconductive layer produced induced magnetization in the gold layer, «overjumping» the superconductor.
The spin and orbital motion gives rise to the magnetization, similar to an electric current circulating in a coil and producing a magnetic field.
One way to produce rapid changes of strain on the subnanosecond scale and, thus, induce magnetization changes is by using surface acoustic waves (SAWs), which are deformation (strain) waves.
