Raman spectroscopy of alpha-FeOOH (goethite) near antiferromagnetic to paramagnetic phase transition
M. V. Abrashev, V. G. Ivanov, B. S. Stefanov +3
Synthetic powder, ore samples and mineral single crystals of goethite (FeOOH) were investigated with polarized Raman spectroscopy at temperatures from 300 K to 473 K. The symme…
Magnetoelectric effect and phase transitions in CuO in external magnetic fields
Zhaosheng Wang, Navid Qureshi, Shadi Yasin +8
Apart from being so far the only known binary multiferroic compound, CuO has a much higher transition temperature into the multiferroic state, 230 K, than any other known material…
Polar domain walls trigger magnetoelectric coupling
Josep Fontcuberta, Vassil Skumryev, Vladimir Laukhin +2
Interface physics in oxide heterostructures is pivotal in material's science. Domain walls (DWs) in ferroic systems are examples of naturally occurring interfaces, where order para…
Ferroelectricity and strain effects in orthorhombic YMnO3 thin films
J. Fontcuberta, I. Fina, L. Fàbrega +3
We report on the dielectric properties of epitaxial [001] and [100]-textured thin films of antiferromagnetic orthorhombic YMnO3 and their variation under compressive epitaxial stra…
Strain-driven non-collinear magnetic ordering in orthorhombic epitaxial YMnO3 thin films
X. Marti, V. Skumryev, V. Laukhin +6
We show that using epitaxial strain and chemical pressure in orthorhombic YMnO3 and Co-substituted (YMn0.95Co0.05O3) thin films, a ferromagnetic response can be gradually introduce…
Magnetization Reversal by Electric-Field Decoupling of Magnetic and Ferroelectric Domains Walls in Multiferroic-Based Heterostructures
V. Skumryev, V. Laukhin, I. Fina +4
We demonstrate that the magnetization of a ferromagnet in contact with an antiferromagnetic multiferroic (LuMnO3) can be speedily reversed by electric field pulsing, and the sign o…
