Opis:: Physical properties of $Gd_2Cu_{2 - x}Co_{x}In$ (x = 0.1, 0.2, 0.3) samples are investigated. The paper brings results of X-ray diffraction, magnetometric as well as specific heat studies. It was found that only sample with x = 0.1 exhibits desired crystal structure. Other compositions show existence of impurities due to lack of dissolution Co atoms. For $Gd_2Cu_{1.9}Co_{0.1}In$ sample the Curie temperature of 92.5 K was evidenced. Thus, an enhancement of ferromagnetic correlations with comparison to $Gd_2Cu_2In$ sample was evidenced. It was found that $Gd_2Cu_{1.9}Co_{0.1}In$ sample exhibits magnetocaloric effect within broad temperature range.

Opis:: The magnetic ordering of the $Tb_2Ni_{1.78}In$ and $Tb_2Ni_2In$ have been studied by neutron diffraction measurements. $Tb_2Ni_{1.78}In$ with the tetragonal $Mo_2FeB_2$-type (space group P4/mbm, tP10) is antiferromagnet with the Néel temperature equal to 20 K. Below this temperature Tb moments form collinear magnetic structure commensurate with the crystal, described by the propagation vectors equal to (1/4, 1/4, 1/2). Magnetic moment equal to 7.60(6) $μ_{B}$ is parallel to c-axis. The Tb_2Ni_2In in the orthorhombic $Mn_2$ $lB_2$-type (space group Cmmm, oC10) was detected as an impurity in the studied sample. It orders antiferromagnetically below ≈ 100 K with collinear moment arrangement described by the propagation vector (1/2, 1/2, 1/2). t 1.6 K $μ_{Tb}$ = 6.33(14) $μ_{B}$ and is parallel to the c-axis.

Opis:: Ternary alloys CeCu$\text{}_{5-x}$In$\text{}_{1+x}$ were studied by means of magnetic and electrical resistivity measurements. In CeCu$\text{}_{5}$In a coherent Kondo state without long-range magnetic order develops at low temperatures. It transforms into an incoherent Kondo state upon small substitution of In for Cu.
