59Co NMR study in Y(Co,Ti)12

Abstract The nuclear magnetic resonance (NMR) of 59 Co nuclei for YCo 12− x Ti x has been measured in zero external field at 4.2 K. The absolute values of the hyperfine field at Co atoms are estimated to be 209, 174 and 131 kOe for YCo 11 Ti and 143, 116 and 89 kOe for YCo 10 Ti 2 . The averaged Co moments for these compounds at 4 K are 1.38 and 0.86 μ B /Co, respectively. These results show that the moments of each Co site decrease almost uniformly.
