During the last years, anisotropic NdFeB films with good performance have been extensively investigated and widely used in application where high BHmax are required, such as microelectromechanical system(MEMS), magnetic recording media and millisize motors or actuators. So, many groups have tried to prepare NdFeB films by sputtering deposition[1]. But the permanent magnet performance of films always...
High-performance permanent magnets for energy-related applications require a high energy product (BH)max. It has been proposed that the two-phase materials exchange-coupled between magnetically hard and soft phases may greatly enhance the energy products.[1,2] More recently, self-assembly of two-component with hard magnetic phase FePt and soft magnetic phase Fe3Pt nanocomposites has successfully enhanced...
Magnetic refrigeration based on the magnetocaloric effect (MCE) is an environmentally friendly and energy efficient solid state cooling technology compared with conventional vapor compression approach In recent years, the interest in large MCE materials including Gd5Si4−xGex, LaFe13-xSix, MnFeP(As, Ge), Ni-Mn-based Heusler alloys, and rare-earth manganites has grown considerably due to their potential...
Magnetic properties and magnetocaloric effect were investigated on LaPrFeSiH melt-spun ribbons. It was found that NaZn -type phase could be obtained easily owing to that the segregation of -Fe phase was suppressed obviously by adding appropriate amount of La after a short time annealing for melt-spun ribbons. For the La Pr Fe...
