Scientists Have Created an Energy-Efficient Alloy for Future Electronics

Researchers at the University of Minnesota have introduced a new nickel-tungsten alloy, Ni4W, which has the potential to change the approach to creating data storage and processing systems in modern electronics.

An Alternative to Traditional Memory Without External Magnets

The Ni4W alloy demonstrates a unique ability to change its magnetic state without the need for external magnetic fields, which is critical for reducing energy consumption. This opens up the prospect of more economical operation of devices such as smartphones, laptops, and data centers.

Ni4W is made from inexpensive and widely available materials, making it suitable for large-scale industrial production. It is easily processed using standard methods, which significantly speeds up the process of integration into existing technology chains.

Prospects

The study showed that Ni4W is capable of generating spin currents in different directions, providing effective magnetization control, a key characteristic for future spintronic devices. According to Professor Jian-Ping Wang, this will enable the creation of faster and less energy-intensive data recording systems.

Thanks to its low cost and efficiency, the alloy can be incorporated into everyday devices, from smart watches to mobile phones.
