Review article on rare earth magnets published

CMI researchers at Ames Laboratory conducted the research for this CMI highlight on a review article published about on rare-earth-TM5 magnets

The PDOS of distinct 2c and 3g2 Co sites along the [100] and [001] directions for different electron density functionals. The shaded regions indicate the DOS for the in-plane [100] axis, whereas the solid lines indicate the DOS along the uniaxial [001] direction. The difference between these curves is an important contribution to magnetic anisotropy.
