New Delhi: Scientists from the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) have found a mechanism of electrical polarization by magnetic ordering in MnBi2S4, pointing in direction of new instructions in knowledge storage know-how.

Led by Professor A. Sundaresan, the analysis into magnetoelectric multiferroics, specializing in the novel mineral MnBi2S4, has been revealed in PHYSICAL REVIEW B. The examine reveals MnBi2S4’s capacity to exhibit ferroelectricity as a consequence of particular magnetic constructions, a discovering that’s uncommon and worthwhile for purposes comparable to spintronics and digital reminiscence gadgets.

Utilizing high-resolution neutron diffraction, the analysis workforce uncovered magnetic constructions in MnBi2S4, together with spin density waves, cycloidal and helical spin constructions. These constructions contribute to the fabric’s magnetic ordering at low temperatures (27, 23, and 21.5 Kelvins) and are essential for inducing ferroelectricity.

Professor Sundaresan highlighted the invention’s significance in understanding magnetoelectric coupling, noting that this conduct in MnBi2S4 has not been reported beforehand. This development might result in the event of energy-efficient knowledge storage applied sciences that require much less power for knowledge writing processes.

The analysis was supported by the Sheikh Saqr Laboratory and International Centre for Materials Science at JNCASR, with monetary help from DST, SERB, and the Government of India. Neutron beam time was offered by the Science and Technology Facility Council (STFC UK).
