A team of scientists from Ames National Laboratory has developed a new machine learning model for discovering critical-element-free permanent magnet materials. The model predicts the Curie temperature of new material combinations. It is an important first step in using artificial intelligence to predict new permanent magnet materials. This model adds to the team's recently developed capability for discovering thermodynamically stable rare earth materials. The work is published in Chemistry of Materials.

Sans ce test d'imagerie médicale, qui peut sembler « difficile » aux patients, il est impossible d'identifier des lésions spécifiques qui sont à l'origine de lésions spécifiques
Un nanomatériau 2D constitué de molécules organiques liées à des atomes métalliques dans une géométrie spécifique à l'échelle atomique présente des propriétés électroniques et magnétiques non négligeables dues à de fortes interactions entre ses électrons.
A new estimate of the strength of the magnetic field around the muon - a subatomic particle similar to but heavier than an electron - bridges the gap between theoretical and experimental measurements, bringing it in line with the Standard Model that has guided particles in physics for decades .
The reversal of the Earth's magnetic poles and the temporary collapse of the global magnetic field around 42,000 years ago could have triggered solar storms, many environmental changes and the extinction of Neanderthals, according to a new study.
