Opis:: We present results of transport and magnetic properties of three single-crystalline samples of the intermediate valence small-gap semiconductor SmB$\text{}_{6}$ at low temperatures. The received resistivity dependences of the samples below 0.5 K exhibit an activated behavior with an energy gap of a few mK. The temperature dependences of the magnetic susceptibility show an increase below 15 K which can be accounted for by impurities, by bare Sm$\text{}^{3+}$ ions or by a small amount of in-gap magnetic 4f$\text{}^{5}$5d$\text{}^{1}$ states.

Opis:: The antiferromagnetic ground state has been studied by transverse magnetoresistance, heat capacity and magnetization measurements, which were carried out on high quality single crystals of $Tm_{0.996}Yb_{0.004}B_{12}$ dodecaboride in strong magnetic fields at liquid helium temperatures. Both antiferromagnetic-paramagnetic (AF-P) and spin-orientation (AF1-AF2) phase transitions have been observed, and allowed to construct a complicated magnetic H-T phase diagram for this compound. Strong magnetoresistance anisotropy was found both in AF states (ρ(H||[110])/ρ(H||[111])~ 1.2 at H~ 20 kOe) and at the critical field of AF-P transition $(H_{N}[100]$/$H_{N}[111]$~ 1.25) in this magnetic metal with a simple fcc crystal structure.
