Overview
This work is a study of paramagnetic phase of the compound using various experimental techniques ErCo2 (XMCD, SANS, magnetization and magnetic susceptibility), which has led to propose a new phase in the magnetic phase diagram ErCo2 in subnet which presents a varied phenomenology Co � a. Furthermore, it has made a study of magnetic order transitions and the magnetocaloric effect of the compounds where R = Nd RCO2, Pr, Tb, Dy, Ho and Er.
