Ferroelectric properties controlled by magnetic fields in DyMn2O5
D. Higashiyama, N. Kida, S. Miyasaka +2
Cross-correlation between magnetic and dielectric properties has been attracting renewed interest because of the fundamental as well as technological importance of controlling the…
Driving mechanisms behind the various phases in manganese perovskites revealed by Mn 2p resonance photoemission
A. Sekiyama, H. Fujiwara, A. Higashiya +4
Unusual temperature and doping dependence of the Mn 3d spectral functions of manganese perovskites Nd1-xSrxMnO3 has been revealed by the high-resolution Mn 2p-3d resonance photoemi…
Magnetic Anisotropy in La_0.8Sr_0.2MnO_3: Electron Spin Resonance
J. Deisenhofer, H. -A. Krug von Nidda, A. Loidl +4
We report on Ferromagnetic-Resonance experiments in a single crystal of La_0.8Sr_0.2MnO_3 in the temperature range from 4 to 300 K. The observed anisotropy of the resonance line ch…
Microscopic spin interactions in the CMR manganites
J. A. Fernandez-Baca, Pengcheng Dai, H. Kawano-Furukawa +5
Using inelastic neutron scattering we measured the microscopic magnetic coupling associated with the ferromagnetic (FM) clusters of the ``colossal magnetoresistance'' (CMR) compoun…
Fermi surface of Sr2RuO4 from angle resolved photoemission
A. Damascelli, K. M. Shen, D. H. Lu +9
We investigated the low-energy electronic structure of Sr2RuO4 by angle-resolved photoemission spectroscopy (ARPES) focusing, in particular, on the controversial issues of the Ferm…
Orbital Ordering Induced Antiferromagnetic Spin Fluctuations in the Ferromagnetic State of 50 % Hole-doped Manganites: Pr{1/2}Sr{1/2}MnO3 and Nd{1/2}Sr{1/2}MnO3
H. Kawano, R. Kajimoto, H. Yoshizawa +3
We report inelastic neutron scattering results on the spin dynamics in the 50 % hole-doped manganites, Pr{1/2}Sr{1/2}MnO3 and Nd{1/2}Sr{1/2}MnO3. In the paramagnetic phase, these s…
