Magnetic properties and the magnetic phase transitions in $R_{5}Rh_{4}Ge_{10}$ (R = Tb-Tm) compounds

The magnetic data for $R_{5}Rh_{4}Ge_{10}$ (R = Tb, Dy, Ho, Er, and Tm) compounds was investigated by means of the dc magnetization and dc and ac magnetic susceptibility. At low temperature all these compounds are antiferromagnets. For these with R = Tb, Ho and Er below $T_{N}$ the additional phase transitions are observed. The obtained data are compared with the neutron diffraction results
