Opis:: Magnetic measurements of $HoAl_{2}$ are reported. The compound crystallizes in the cubic $MgCu_{2}$-type crystal structure. $HoAl_{2}$ exhibits two successive magnetic transitions: below $T_{c}$ = 29 K a ferromagnetic order is formed while anomaly at $T_{t}$ = 20 K is related to reorientation of magnetic moment. Near transition temperatures a magnetocaloric effect with magnetic entropy changes -$ΔS_{m}$ equal to 6.3 J/(mol K) at $T_{c}$ and 5.0 J/(mol K) at $T_{t}$ for an external field $μ_{0}H$ = 9 T is observed.

Opis:: The magnetic properties of the ternary intermetallic RRhGe (R = Dy and Tm) were investigated by magnetic and neutron diffraction measurements. These compounds crystallize in a TiNiSi-type orthorhombic structure and are antiferromagnets with the Néel temperature 20 K (R = Dy) and 6.2 K (R = Tm). The neutron diffraction data reveal that the magnetic order in TmRhGe is collinear with the magnetic unit doubled along the b-axis respective to the crystal one.

Opis:: The magnetic properties including the magnetic structure were determined by magnetometric and neutron diffraction measurements of the polycrystalline samples. RCuGe compounds are antiferromagnets at low temperatures, with T$\text{}_{N}$ ranging from 2.2 K for R = Pr to 17 K for R = Gd. The external magnetic field causes a change in the type of the magnetic ordering from antiferro- to ferromagnetic state. From the neutron diffraction data the magnetic structure of all RCuGe compounds are determined. In the case of ErCuGe below T$\text{}_{N}$ an additional phase transition is observed. The obtained experimental data are discussed in terms of an exchange interaction of the RKKY-type and crystalline electric field.

Opis:: X-ray diffraction and magnetic measurements of $R_2Ni_{2 - x}In$ (R = Ho, Dy, x = 0.3 and R = Gd, Tb, Er, x = 0.22) compounds are reported. The compounds crystallize in the tetragonal $Mo_2FeB_2$-type crystal structure (space group P4/mbm). Magnetic measurements reveal antiferromagnetic order with the Néel temperatures $T_{N}$ equal to 26.4 K (Gd), 20.2 K (Tb), 8.3 K (Dy), 7.1 K (Ho), and 6.3 K (Er). For R = Gd, Tb and Er an additional phase transition below $T_{N}$ is observed at 13.5, 13.1, and 5.0 K, respectively.
