MnBi2S4

Researchers have identified a unique mechanism of electric polarization via magnetic ordering in a novel mineral named “MnBi2S4”, which can be useful for energy efficient data storage.

  • Magnetoelectric multiferroics are a special class of materials popular among the research fraternity for their rarity and unique properties.
  • Interestingly, these materials can exhibit both magnetism and ferroelectricity simultaneously.
  • This dual property is particularly fascinating, as materials typically possess either magnetism or ferroelectricity.
  • Finding a single material with both these properties, is therefore, rare and valuable.
  • MnBi2S4 is also known as mineral graţianite and belongs to the ternary manganese chalcogenide family.
