Embodiment 1
[0098] (NiFe 2 o 4 Synthesis)
[0099] According to the method disclosed in Non-Patent Document 10, NiFe 2 o 4 The synthesis is as follows.
[0100] First, the Ni(NO 3 ) 2 ·6H 2 O and Fe(NO 3 ) 3 9H 2 O was dissolved in deionized water to prepare the mixture. In this mixture, Ni(NO 3 ) 2 ·6H 2 O to Fe(NO 3 ) 3 9H 2 The molar ratio of O is 1:2.
[0101] The mixture was mixed for 2 hours, and then, an ammonia solution was added thereto while mixing to adjust the pH of the mixture to 8.
[0102] Next, the obtained solution was poured into a Teflon-coated stainless steel autoclave, and heated to 230° C. at a heating rate of 5° C. / min, and the temperature of the solution was maintained for 30 minutes.
[0103] Then, the autoclave was air-cooled to room temperature, and the precipitate thus obtained was washed several times by distilled water, and subsequently, the precipitate was dried at 80°C.
[0104] The obtained precipitate was analyzed by X-ray diffraction (...
