内容記述 | We prepared L10 ordered Fe50Pt50 thick-films on Cu substrates using the electroplating method and evaluated their high-temperature properties in the temperature range of 25-200○C. The Hc and the (BH)max at 150○C for the Fe50Pt50 films annealed by ordinary annealing method(700○C, 60 min) were 500 kA/m and 50 kJ/m3, respectively, and the thermal coefficient of Hc was -0.3%/○C. To improve the high-temperature properties, we employed a flash annealing method using an infrared furnace (8 kW). The flash annealing method improved the hightemperature properties (Hc = 700 kA/m, (BH)max = 70 kJ/m3 at 150○C) and the thermal coefficient (-0.21%/○C). The thermal stability of the films is comparable to those for Sm-Co-system magnets and better than for Nd-Fe-B-system ones. We, therefore, found the L10 ordered Fe50Pt50 films prepared by the electroplating and the flash annealing are one of the hopeful small magnets in the wide temperature range. |
