Rounding of a first-order magnetic phase transition in Ga doped La0.67Ca0.33MnO3
TL;DR: In this article, the effect of disorder on the critical properties of the ferromagnetic phase transition in colossal magnetoresistive manganite La0.67Ca0.33MnO3 has been studied by substituting Ga for Mn.
Journal ArticleDOI
A model system for strain effects: epitaxial magnetic films on a piezoelectric substrate
K. Dörr,O. Bilani-Zeneli,Andreas Herklotz,A. D. Rata,K. Boldyreva,J.-W. Kim,M. C. Dekker,K. Nenkov,Ludwig Schultz,M. Reibold +9 more
TL;DR: In this article, the strain-dependent magnetization of two-phase magnetoelectric multiferroics was investigated on pseudocubic Pb(Mg1/3Nb2/3)0.72Ti0.28O3(PMN-PT) substrates.
Journal ArticleDOI
Metamagnetic effects in epitaxial BaFe1.8Cr0.2As2 thin films
J. Engelmann,J. Engelmann,K.H. Müller,K. Nenkov,Ludwig Schultz,Ludwig Schultz,Bernhard Holzapfel,Bernhard Holzapfel,S. Haindl +8 more
TL;DR: In this paper, resistive measurements indicate the existence of two transitions at temperatures of about 80 k and 40 k. The transition at 80 k is attributed to the structural transition from the high temperature tetragonal phase to the low temperature orthorhombic phase accompanied with the magnetic transition from a paramagnetic to an antiferromagnetic state as known for doped bulk systems.
Journal ArticleDOI
Approaches towards ferroelectric control of thin film magnetism
TL;DR: Fues et al. as discussed by the authors discuss three different approaches towards ferroelectric control of thin film magnetism and recent experimental results, and discuss the effect of piezoelectric gate strain.
Journal ArticleDOI
Strain response of magnetic order in perovskite-type oxide films
Andreas Herklotz,M. D. Biegalski,Hans M. Christen,Er-Jia Guo,K. Nenkov,A. D. Rata,Ludwig Schultz,Kathrin Dörr +7 more
TL;DR: An experimental approach for the evaluation of how elastic strain in thin epitaxial films alters their magnetic order is introduced, and a strain-driven transition from a ferromagnetic to a magnetically disordered phase has been observed in epitaxials La0.8Sr0.2CoO3 films.
