Autor: Bernhardt, Felix, Verhoff, Leonard M., Schäfer, Nils A., Kapp, Alexander, Fink, Christa, Nachwati, Wafaa Al, Bashir, Umar, Klimm, Detlef, Azzouzi, Fatima El, Yakhnevych, Uliana, Suhak, Yuriy, Schmidt, Harald, Becker, Klaus-Dieter, Ganschow, Steffen, Fritze, Holger, Sanna, Simone

The ferroelectric to paraelectric phase transition in LiTaO$_3$ and in pure as well as Mg doped LiNbO$_3$ is investigated theoretically by atomistic calculations in the framework of the density functional theory, as well as experimentally by calorime

Report

Phase Transformation in Lithium Niobate-Lithium Tantalate Solid Solutions (LiNb$_{1-x}$Ta$_x$O$_3$)

Autor: Azzouzi, Fatima El, Klimm, Detlef, Kapp, Alexander, Verhoff, Leonard M., Schäfer, Nils A., Ganschow, Steffen, Becker, Klaus-Dieter, Sanna, Simone, Fritze, Holger

The investigation of the structural phase transition in the vicinity of the Curie temperature $T_c$ of LiNb$_{1-x}$Ta$_x$O$_3$ crystals is motivated by the expected combination of advantageous high-temperature properties of LiNbO$_3$ and LiTaO$_3$, i

Mechanochemická reakcia v spinelovom ferite

Autor: Becker Klaus Dieter, Menzel Marcus, epelák Vladimír

Publikováno v: Acta Montanistica Slovaca, Vol 5, Iss 3, Pp 274-278 (2000)

Mechanicky indukované redukèné reakcie v tuhých látkach patria medzi významné mechanochemické procesy. V práci sú Mössbauerovou spektroskópiou, prákovou röntgenovou difrakciou a termickou analýzou tudované zmeny vo ferite horèíka (M
