Effect of preparation method and purity on the specific heat and magnetic susceptibility of Nd sub 2 CuO sub 4

Low-temp. specific heat shows that coprecipitation of Nd and Cu hydroxides (but not oxalates) gives a pure Nd sub 2 CuO sub 4 insulator with an upturn at 1.5 K of 6.1 J mol- sup 1 K- sup 1 . The absence of rounded peaks (observed in samples prepared via oxalates) and of gamma contribution results fr...

Description
Summary:Low-temp. specific heat shows that coprecipitation of Nd and Cu hydroxides (but not oxalates) gives a pure Nd sub 2 CuO sub 4 insulator with an upturn at 1.5 K of 6.1 J mol- sup 1 K- sup 1 . The absence of rounded peaks (observed in samples prepared via oxalates) and of gamma contribution results from nonexistence of Cu sup + and Nd sub 2 O sub 3 impurity.
