چکیده انگلیسی
The itinerant-electron metamagnetic transition of La(Fe0.88Si0.12)13 becomes indistinct after immersion in distilled-water containing about 8Â ppm of the dissolved oxygen (DO) concentration because of aqueous corrosion. However, the aqueous corrosion of La(Fe0.88Si0.12)13 is significantly suppressed by reducing the DO concentration. Thus, isothermal magnetic entropy change after immersion for 30Â days in deaerated distilled-water with a DO concentration less than 0.1Â ppm is larger than that after immersion for 5Â days in distilled-water containing about 8Â ppm of the DO concentration. Consequently, the reduction of the DO concentration is effective for preservation of the excellent magnetocaloric effects of La(Fe0.88Si0.12)13 in an aqueous solution, which is a promising heat transfer fluid of room-temperature magnetic refrigeration.
