Modifying the magnetoelectric coupling in TbMnO by low-level Fe substitution
A. Maia, R. Vilarinho, C. Kadlec +6
We report a comprehensive study of the low-level substitution of Mn by Fe effect on the static and dynamic magnetoelectric coupling in TbMnFeO (,…
Systematic study of Mn-doping trends in optical properties of (Ga,Mn)As
T. Jungwirth, P. Horodyska, N. Tesarova +13
We report on a systematic study of optical properties of (Ga,Mn)As epilayers spanning the wide range of accessible substitutional Mn_Ga dopings. The growth and post-growth annealin…
Terahertz and infrared spectroscopic evidence of phonon-paramagnon coupling in hexagonal piezomagnetic YMnO3
C. Kadlec, V. Goian, K. Z. Rushchanskii +5
Terahertz and far-infrared electric and magnetic responses of hexagonal piezomagnetic YMnO3 single crystals are investigated. Antiferromagnetic resonance is observed in the spectra…
Multiple soft-mode vibrations of lead zirconate
J. Hlinka, T. Ostapchuk, E. Buixaderas +7
Polarized Raman, IR and time-domain THz spectroscopy of orthorhombic lead zirconate single crystals yielded a comprehensive picture of temperature-dependent quasiharmonic frequenci…
Two Displacive Ferroelectric Phase Transitions in Multiferroic Quadruple Perovskite
A. Maia, M. Kempa, V. Bovtun +6
We report on the microwave, terahertz (THz), infrared and Raman spectroscopic studies of ceramics, shedding more light into the nature of two structural phase tran…
A frustrated antipolar phase analogous to classical spin liquids
G. Bastien, D. RepÄek, A. Eliáš +17
The study of magnetic frustration in classical spin systems was motivated by the prediction and discovery of classical spin liquid states. These uncommon magnetic phases are charac…
