Abstract :
The development of new permanent magnet materials is of particularly importance since the high-performance Nd2Fe14B are expensive due to the limited reserves of rare earth Nd, Tb, Dy on the earth. In the past several years, much attention has been attracted to the permanent magnet without rare earth, such as Zr2Co11, HfCo7 and Mn-based alloys, and excellent performance has been observed. For example, the achieved energy products can be as high as 19.5MGOe in Zr2Co11 : Fe-Co nanocomposites. Here, we report strain-induced high coercivity in the Co-based La0.7Sr0.3CoO3 (LSCO) films.
