Curie temperature of nickel
Webcobalt increase the Curie temperature of nickel and cobalt in- creases the Curie temperature of iron. In many binary phase diagrams, the temperature dependence ... WebFor compounds with Ni, on the other hand, no magnetic moment at the nickel atoms is observed, and the magnetic interaction involves only the R sublattice [9,10]. Hence, these compounds are magnetically ordered at relatively low temperatures that reach even below 40 K with the exception of GdNi 2, where the Curie temperature is equal to 75 K .
