Magnetic properties of hexagonal RNi4Si (R = rare earth) compounds

  • 1. Institute of Molecular Physics, Polish Academy of Sciences, Smoluchowskiego 17, 60-179 Poznan (Poland)

Description

RNi4Si (R = rare earth) compounds have been studied by means of the X-ray powder diffraction, magnetization and magnetic susceptibility measurements. These compounds crystallize in the hexagonal CaCu5-type of structure, space group P6/mmm. Apart from La, Ce, Pr and Yb, these compounds order ferromagnetically between 5.7 K (Tm) and 22 K (Gd). A strong thermomagnetic irreversibility is observed, i.e., the temperature dependence of the magnetic moment is different in the zero-field cooling (ZFC) and field-cooling (FC) mode. The difference between the ZFC and FC magnetization curves could be induced by the magnetocrystalline anisotropy of the R ion
