Phase transitions in multiferroic BiFeO3 crystals, thin-layers, and ceramics: Enduring potential for a single phase, room-temperature magnetoelectric 'holy grail'
A. M. Kadomtseva, Yu. F. Popov, A. P. Pyatakov +3
Magnetic phase transitions in multiferroic bismuth ferrite (BiFeO3) induced by magnetic field, epitaxial strain, and composition modification are considered. These transitions from…

Relaxations as key to the magnetocapacitive effects in the perovskite manganites
F. Schrettle, P. Lunkenheimer, J. Hemberger +4
We present a detailed dielectric study of the relaxation effects that occur in several perovskite rare-earth manganites, including the multiferroics TbMnO3 and DyMnO3. We demonstra…

Differentiable functions of quaternion variables
S. V. Ludkovsky, F. van Oystaeyen
We investigate differentiability of functions defined on regions of the real quaternion field and obtain a noncommutative version of the Cauchy-Riemann conditions. Then we study th…
