Abstract : The use of neutron diffraction to determine the magnetic structure of powder samples YCo5 and NdCo5 is described. Experimental results are presented and compared to a theoretical model. The system used to control the sample temperature is described with its performance characteristics. Results show that there is no detectable magnetic moment attributed to the yttrium atoms in the YCo5 compound. Investigation of the NdCo5 samples shows that the magnetization vector rotates from the c-axis towards the a-axis as the temperature is lowered from room temperature to 108 degrees K. (Author)
