Opis:: Magnetism of borides which contain the $B_{12}$ icosahedra as a structural building block are attracting increasing interest since they exhibit unexpectedly strong magnetic interactions, despite being magnetically dilute f-electron insulators. The magnetic behavior among the different compounds has also been found to be diverse. The f-electron dependence of magnetic B_{12} icosahedra borides is compared, and found to be different from conventional mechanisms. The $TbB_{25}$ system is also investigated further and the transition is assigned to a typical antiferromagnetic transition.

Opis:: Point-contact spectroscopy studies of the superconducting energy gap and the electron-phonon coupling mechanism are performed on the boron rich $YB_6$ and $ZrB_{12}$ single crystals. The obtained values of the superconducting energy gaps suggest the strong coupling with 2 Δ/$k_{B}T_{c}$≈ 4.2 for $YB_6$ and 2 Δ/$k_{B}T_{c}$≈ 4.15 for $ZrB_{12}$. We have observed the dominant soft phonon modes mediating superconductivity in the both samples at energy ≈ 8 meV for $YB_6$ and ≈ 11 meV in $ZrB_{12}$, respectively.

Opis:: Magnetic ordering in $TbB_{66}$ and $GdB_{66}$ was investigated at very low temperatures. Measurements of ac susceptibility have shown rather clear features of magnetic ordering below 1 K, at 0.34 K for $TbB_{66}$ and at 0.20 K for $GdB_{66}$. However, no clear evidence of long range magnetic order was found by neutron scattering experiments. Reasons leading to these observations are discussed.

Opis:: Magnetoresistivity measurements on a superconducting system of $YB_{6}$ ($T_c$ ≈7.5 K) down to 60 mK at hydrostatic pressures up to 47 kbar are presented. The superconducting transition temperature, as well as the third critical field $H_{c3}$ reveal a linear decrease with increasing pressure with slopes of d ln $H_{c3}$/dp=-1.1 %/kbar, and d ln $T_c$/dp=-0.59 %/kbar. From the latter a critical pressure, $p_c$ ≈ 170 kbar, at which $T_c$ vanishes, is determined.
