Improvement in the magnetic properties of PLD (Pulsed Laser Deposition)-fabricated isotropic Fe-Pt film magnets by controlling laser energy density, which strongly affects the numbers and/or size of droplets, was carried out. The use of laser energy density range from 10 to 25 J/cm2 enabled us to obtain Fe-Pt films with relatively a little amount of droplets. Resultantly, we could enhance the value of (BH)max up to approximately 125 kJ/m3 which is comparable compared with that of a sputtering-made Fe-Pt film magnet.
