One of the key ingredients to the properties of permanent magnets is the large uniaxial magneto-crystalline anisotropy which usually arises from rare-earth elements such as neodymium or dysprosium. Their cost, limited availability and environmental impact has motivated the scientific community to look for new magnetic compounds with less rare-earth. The challenge is to obtain large magneto-crystalline anisotropy with non-rare-earth elements. We studied the magnetic anisotropy of single crystals of new materials grown using the solution growth technique. We found large magnetic anisotropy in several Mn, Fe and Co based ferromagnets and discuss their suitability for permanent magnet applications. We discovered new ferromagnets such as HfMnP and ZrMnP which have large anisotropy, we study the change from planar to axial anisotropy with temperature and substitutions in Fe2B alloys and we report on axial anisotropy in Fe5B2P.
