Reduced crystal symmetry as origin of the ferroelectric polarization within the incommensurate magnetic phase of TbMn2O5
N. Narayanan, P. J. Graham, P. Rovillain +9
The precise crystal symmetry and hence the emergence of the electric polarization still remains an open question in the multiferroic materials MnO ( = rare-earth, Bi,…
Magnetic properties of the low-dimensional spin-1/2 magnet α-Cu_2As_2O_7
Y. C. Arango, E. Vavilova, M. Abdel-Hafiez +11
In this work we study the interplay between the crystal structure and magnetism of the pyroarsenate α-Cu_2As_2O_7 by means of magnetization, heat capacity, electron spin resonance…
Interface driven magnetoelectric effects in granular CrO2
A. Bajpai, P. Borisov, S. Gorantla +5
Antiferromagnetic and magnetoelectric Cr2O3-surfaces strongly affect the electronic properties in half metallic CrO2. We show the presence of a Cr2O3 surface layer on CrO3 grains b…
Evidence for Jahn-Teller distortions at the antiferromagnetic transition in LaTiO
J. Hemberger, H. -A. Krug von Nidda, V. Fritsch +8
LaTiO is known as Mott-insulator which orders antiferromagnetically at K. We report on results of thermal expansion and temperature dependent x-ray diffraction…
