First the team investigated how angle θ between ferromagnetic
layer magnetizations depends on angle φ between the axes of the antiferromagnets (fig. 1a, top).

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.
When scientists changed the
magnetization directions in two
layers, making them parallel, this effect almost disappeared: field intensity experienced twentyfold decrease.
This method gave the researchers the possibility to understand, how the
magnetization proceeds in different
layers of the sample.
This current of heat creates a separation of electron spins that then diffuse through the Cu heat sink and affect the
magnetization of a second ferromagnetic
layer, CoFeB, causing the
magnetization to tilt and then precess.
