• In order to investigate the heavy-fermion like behavior of amorphous alloy Ce x Mn 100 - x , the NMR measurements of 55Mn ( I = 5 2 ) in Ce 65Mn 35 have been carried out from 4.2 to 270 K using powdered sample. A broadened NMR spectrum containing five NQR lines split due to NQR interaction is observed. Quadrupole coupling constant 3 e 2 Qq / 2 I ( 2 I - 1 ) h is gradually changed from about 1.8 MHz at 4.2 K to about 1.6 MHz at 270 K. Temperature dependence of the line width is expressed in the Curie–Weiss law with θ p = - 10.5 K . The value of Knight shift would be almost constant from 4.2 to 270 K.
