Unusual metal oxide shows signs of magnetism under lattice strain in ultrathin layers

Ruthenium dioxide (RuO2) is a metal oxide that commonly serves as an important metallic conductor, quantum material and industrial electrocatalyst. While there have been debates surrounding the magnetic properties of RuO2, it is generally thought to be nonmagnetic in its bulk form. But now, a new study, published in Science Advances, has found that very thin

The top 3

  1. Neodymium Magnets: Unrivaled Strength: Neodymium magnets are currently the strongest commercially available permanent magnets, with grades reaching up to N52 and a magnetic energy product of 35 to 52 MGOe, making them ideal for electronic products like hard drives and mobile phones.
  2. Samarium Cobalt: High Temperature Resilience: Samarium cobalt magnets, while slightly less powerful than neodymium, offer superior resistance to high temperatures (up to 350°C) and corrosion, making them ideal for aerospace, defense, and medical applications.
  3. Alnico Magnets: Extreme Temperature Stability: Alnico magnets, composed of aluminum, nickel, and cobalt, are highly valued for their exceptional temperature stability, maintaining magnetic performance from -270°C up to +550°C, and good corrosion resistance.
