The influence of substitution of Co for Ni in Sm(Ni_{1-x}Co_{x})₃, where x=0.0, 0,1, 0.2, on the structural and magnetic properties has been investigated. Samples with x= 0.0 and 0.2 were subjected to grinding in a high energy ball mill. The presence of a PuNi₃ type of crystal phase was evidenced for bulk crystalline and powders specimens. With an increase in the cobalt content, an increase at T_{c}...
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...
