Study of Transition Element doped Oxide based Permanent Magnets

The detailing about Hexaferrite Strontium based Hexa-ferrites are well used and saturated having a history of more than 100 years. The questions automatically arises that what is the requirement now from this material, so
as we know that this particular material has a huge industrial application. Today industries requirement is
to enhance the coercivity and retentivity value of the magnetic material and therefore having this as the motivation we doped a number of transition elements with various combinations and try to solve this particular challenge for the industry.
