Quantum electric-dipole liquid on a triangular lattice [PDF]

, 2015
Geometric frustrations and quantum mechanical fluctuations may prohibit the formation of long-range ordering even at the lowest temperature, and therefore liquid-like ground states could be expected.

LTCC-technology for Producing Hexaferrites [PDF]

Journal of Nano- and Electronic Physics, 2016
In the review examined the possibility of using LTCC-technology for obtaining hexaferrites as reaction additives glasses Bi2O3-B2O3-SiO2-ZnO (BBSZ) and BaCu (B2O5) (BCB) to reduce the sintering temperature. It is shown that compatibility between hexaferrites with the addition BBSZ, BCB and silver paste, which is a key requirement in the manufacturing ...
