However, it is recognized that these family of magnets still presents low thermal stability and poor corrosion resistance, which have been in some sense, acting as a barrier to many applications where the temperature or the environmental humidity is found to be even slightly higher than the optimal working condition.  aMagnetismo  aMicroanálise  aSEM1 aMELLO, M.1 aFERRANTE, M.  tIn: INTERNATIONAL CONGRESS ON ELECTRON MICROSCOPY=MEMORIAS DEL CONGRESO INTERNACIONAL DE MICROSCOPIA ELETRÓNICA-ICEM, 14., 1998, Cancún.
