|Title:||Hard magnetic properties of ErCo7-xCux[0.3 <= x <= 1] system|

|Abstract:||We report the observation of excellent hard magnetic properties on purely single phase ErCo7-xCux compounds with x = 0.3, 0.5, 0.8 and 1. Cu substitution leads to a decrease in the saturation magnetization, but enhances the uniaxial anisotropy in this system. The large anisotropy field (similar to 100 kOe) is attributed to the Er and the Co sublattices. Domain wall pinning effect seems to play a crucial role in determining the temperature and field dependences of magnetization in these compounds. The hard magnetic properties obtained at room temperature (RT) are comparable to the best results obtained in other RCo7 based materials. (c) 2006|
