According to TUK, the physicists have shown for the first time, that magnon current flow is possible in an integrated magnon circuit, in which case the components are only being connected two dimensionally.
It is said that these quantum particles can transport significantly more information when compared to electrons, require less energy and produce less heat.
In a published study, the scientists have described the magnon integrated circuit in which information is carried by way of these particles. In this case, conductors and line crossings are necessary to connect the individual switching elements.
The researchers claim to have developed such a junction for magnons in their simulations.
“We have managed to include this phenomenon into our calculations which is already well-known in physics and will be placed into application for the first time in magnonics” said lead author, Qi Wang. “When two magnon conductors are placed rather closely together, the waves communicate to a certain point with each other. This means that the energy of the waves will be transferred from one conductor to the next.”
Associate professor, Andrii Chumak, who is a researcher with his own sub-group in the Magnetism Research Group at TUK, have also harnessed this method to wire circuit elements on a magnonic chip. Chumak says that the stimulated results demonstrate that they can be used for junctions without any three-dimensional bridge construction.
“In our circuits, we use two dimensional connections, in which the magnon conductors only need to be placed close enough to each other” explained Qi Wang.
This connection point is referred to as a directional coupler. The researchers intend to layout the first magnonic circuit with the help of this model.
The simulated components are within the nanometer regime, but the information density using magnons is said to be greater.
The hope is that these circuits could save material and therefore, cost when it comes to the future production of computer components.
