At the interface where domains of different
magnetization direction meet, the magnetization has to rotate from one direction to another in a so - called domain wall.
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.

Within a skyrmion, the
direction of the atoms» poles twists until the
magnetization in the center points in the opposite
direction of the
magnetization outside.
Here, each atom is indicated by a cone that points in the
direction of its
magnetization.
In a 2008 paper in Science, Parkin and colleagues demonstrated the beginnings of a racetrack memory based not on skyrmions, but on magnetic features called domain walls, which separate regions with different
directions of
magnetization in a material.
Here, cones point in the
direction of each atom's
magnetization.
The scientists measured how this voltage changed with the
direction of the
magnetization to isolate the fingerprints of the spin Nernst effect.
Then, they altered the
direction of the insulator's
magnetization, which changed whether the spin current could flow through the insulator.
However, in the Gd22 % sample, wave - like
magnetization modulation propagated isotropically along the radial
direction.
The
magnetization in the branches can be oriented in two different
directions along the nanowire axis, where each
direction would serve as the «0» and «1» necessary for data storage and processing.
The most obvious approach would be to apply a magnetic field in the
direction in which the
magnetization runs in the tiny nanowires.
