Spintronics: the electronics of the future could be antiferromagnetic
It is an important step forward in spintronics: the magnetic state of certain materials can be switched using surface induced strain. All our electronics are based on electrical charges being transported from one place to another. Electrons move, current flows, signals are transmitted by applying an electrical voltage.

Unconventional magnets: stress reduces frustration
Unconventional magnets: stress reduces frustration
An international research team recently demonstrated how magnetism can be actively changed by pressure. Magnetism occurs depending on how electrons behave. For example, the elementary particles can generate an electric current with their charge and thereby induce a magnetic field. However, magnetism can also arise through the collective alignment of the magnetic moments (spins) in a material.

Highly Charged Ions Melt Nano Gold Nuggets
Highly Charged Ions Melt Nano Gold Nuggets
Tiny structures made of gold can be specifically manipulated by ion bombardment at TU Wien (Vienna) - surprisingly, the decisive factor is not the force of the impact. Normally, we have to make a choice in physics: Either we deal with big things - such as a metal plate and its material properties, or with tiny things - such as individual atoms.

New measurements call spin liquids into question
New measurements call spin liquids into question
Is it possible to transmit information through a material in the form of electron spins? New measurements show: not in the way that scientists had been working on for decades. It is an old dream of solid-state physics: "spin liquids" are a hypothetical state of matter with exotic magnetic properties.

Microchips of the Future: Suitable Insulators are Still Missing
Microchips of the Future: Suitable Insulators are Still Missing
Until now, hexagonal boron nitride was considered the insulator of choice for miniaturised transistors. New investigations by TU Wien (Vienna) show: this may not be the way to go. For decades, there has been a trend in microelectronics towards ever smaller and more compact transistors. 2D materials such as graphene are seen as a beacon of hope here: they are the thinnest material layers that can possibly exist, consisting of only one or a few atomic layers.

Solar storms as danger for the power grid
Solar storms as danger for the power grid
By Birgit Baustädter Power cuts have a wide variety of causes. Mostly we think of damaged power lines due to wind and weather or unplanned power surges that overload the grid. But solar storms can also lead to them. Electricity is omnipresent in our lives. So omnipresent that we no longer even consciously perceive it.

New Materials for Extra Thin Computer Chips
New Materials for Extra Thin Computer Chips
For a long time, something important has been neglected in electronics: If you want to make electronic components smaller and smaller, you also need the right insulator materials. Ever smaller and ever more compact - this is the direction in which computer chips are developing, driven by industry. This is why so-called 2D materials are considered to be the great hope: they are as thin as a material can possibly be, in extreme cases they consist of only one single layer of atoms.

Electronics Based Systems: The Basis for our Future
Electronics Based Systems: The Basis for our Future
By Birgit Baustädter Electronics-based systems have long since found their way into our everyday lives. Consciously in the form of new technical gadgets and unconsciously in the form of embedded systems. It is therefore impossible to imagine our familiar life without electronics-based systems. But, and here researchers are in agreement, they will continue to shape our environment in the future as the basis for many innovative developments.
