MEPhI helps to create memory nanoelements for satellites

The new magnetic elements are iron-nickel alloy

a

triangles with sides of several hundred nanometers. The new elements have magnetic properties that allow changing the form of the triangular nanostructure – the concavity of the sides and elongation of the tops. Such magnetic nanostructures can function as logic cells because the state of magnetization in its top is explained by the magnetization of two other tops.

Connection of nanomagnetic structures into a system (bidimensional chains) gives an opportunity to create a logic and memory array in which information readout consists of so-called magnet-tunneling contacts at the nanostructure angles.

The advantages of logic and memory arrays based on magnetic nanostructures are radiation resistance, high stability of information storage and energy efficiency. Their power consumption is about 0.1 microwatt, which is an order less than CMOS transistors.
