Pardon my comment, but why on earth would you want to make specialty, rare-earth magnet yourself when there are very wel qualified companies with vast experience at the process? Sounds kin of like wanting information on how to make an integrated circuit i your basement
I am an inveterate Do-It-Yourselfer, but there are limits. You ar
unlikely to save money by trying to make magnets at home. I requires knowledge of and sources for the specific, exotic material and the appropriate mix/alloy for the properties you want, sinterin furnaces, dies and presses, precise temperature control, ability t apply the correct magnetic field while the material is above th Curie temperature, specialty coatings and ability to bake them o (if you use powder coatings) without depolarizing your magnet, etc. etc
"Physics Today" 2003 Buyers' Guide lists a dozen or two magne
manufacturers. Go to

, select (M)agnets permanent (or the category you want), and you get the list
"magnets, permanent" brings up
Angstrom Sciences Inc.
Dexter Magnetic Technologies Inc. Global Equipment-Magnetics Division Integrated Magnetics MagnaPlan Corp. Magnetic Component Engineering Inc. Magstar Technologies National Imports LLC TeachSpin, Inc.
One or more of them may even have what you need as a standard item i
their catalog, or at least have dies to make what you need.
Good luck
