|Ames Laboratory researchers Bruce Harmon and Yongbin Lee have found an accurate way to explain the magnetic properties of lanthanum, cobalt and oxygen (LaCoO3) that has mystified the scientific community for decades. While most materials tend to lose magnetism at higher temperatures, pure LaCoO3 is a non-magnetic semiconductor at low temperatures, but as the temperature is raised, it becomes magnetic.|

Materials scientists at the U.S. Department of Energyâ€™s (DOE) Ames Laboratory have found an accurate way to explain the magnetic properties of a compound that has mystified the scientific community for decades.
PhysOrg picked up the news release on a discovery by Ames Lab researchers of a new family quasicrystals. The discovery has been published online by the journal Nature Materials in an article, â€œA family of binary magnetic icosahedral quasicrystals based on rare earth and cadmium.â€
Scientists at the U.S. Department of Energyâ€™s (DOE) Ames Laboratory have discovered a new family of rare-earth quasicrystals using an algorithm they developed to help pinpoint them. Their research resulted in finding the only known magnetic rare earth icosahedral binary quasicrystals, now providing a â€œmatched setâ€ of magnetic quasicrystals and their closely related periodic cousins.
Physicists at the U.S. Department of Energyâ€™s Ames Laboratory have discovered surprising changes in electrical resistivity in iron-based superconductors. The findings, reported in Nature Communications, offer further evidence that magnetism and superconductivity are closely related in this class of novel superconductors.
