A new magnetic material has been explored for future technologies.

A research group consisting of scientists from RTU MIREA has successfully studied the new quasi-two-dimensional magnet CrTe3. The Russian-Indian team, which included associate professors Alexey Kartsev and Alexander Safronov from the Department of Physics and Technical Mechanics at RTU MIREA, was responsible for modeling and theoretically describing the properties of the material.

“Quasi-two-dimensional magnets represent a completely new class of magnetic materials that exhibit unique characteristics, such as the ability to retain magnetic properties even at thicknesses of just a few atomic layers,” explains Alexey Kartsev, an associate professor at the Institute of Advanced Technologies and Industrial Programming at RTU MIREA. “These materials hold tremendous potential for use in spintronic devices and microelectronic systems due to their special properties.”

Indian researchers synthesized the two-dimensional chromium telluride (CrTe3), which is a quasi-two-dimensional magnet. This material maintains ferromagnetic properties up to a temperature of 224°C, known as the Curie point, after which magnetic ordering is disrupted. Additionally, the material is characterized by significant remanent magnetization, allowing it to retain magnetic properties even after the removal of an external magnetic field.

Based on the synthesized material, a new type of device has been developed for generating electricity—a magneto-acoustic nanogenerator that converts acoustic waves into electrical energy. The main mechanical parameters and sensitivity of the device were tested under various loads.

The research findings have been published in one of the leading high-impact journals in the field of nanotechnology, Small.
