The magnetic and dielectric properties of åkermanite Ca2CoSi2O7 single crystals were investigated in pulsed high magnetic fields. In magnetic fields along the c-axis, Ca2CoSi2O7 shows a magnetization plateau in a wide field range below saturation....

We studied single crystals of BaV13O18, in which V ions with an average valence of + 2.62 (3d(2.38)) form a quasi-fcc lattice. We found that the ground state of the stoichiometric crystal is insulating, whereas that of the off-stoichiometric cryst...
