A-site driven ferroelectricity in strained ferromagnetic L2NiMnO6 thin films
R. Takahashi, I. Ohkubo, K. Yamauchi +6
We report on theoretical and experimental investigation of A-site driven ferroelectricity in ferromagnetic La2NiMnO6 thin films grown on SrTiO3 substrates. Structural analysis and…
Spin-filter tunnel junction with matched Fermi surfaces
T. Harada, I. Ohkubo, M. Lippmaa +5
Efficient injection of spin-polarized current into a semiconductor is a basic prerequisite for building semiconductor-based spintronic devices. Here, we use inelastic electron tunn…
Infrared anomalous Hall effect in SrRuO: Evidence for crossover to intrinsic behavior
M. -H. Kim, G. Acbas, M. -H. Yang +7
The origin of the Hall effect in many itinerant ferromagnets is still not resolved, with an anomalous contribution from the sample magnetization that can exhibit extrinsic or intri…
In-situ photoemission study of Pr_{1-x}Ca_xMnO_3 epitaxial thin films with suppressed charge fluctuations
H. Wadati, A. Maniwa, A. Chikamatsu +7
We have performed an {\it in-situ} photoemission study of Pr_{1-x}Ca_xMnO_3 (PCMO) thin films grown on LaAlO_3 (001) substrates and observed the effect of epitaxial strain on the e…
Determination of the infrared complex magneto-conductivity tensor in itinerant ferromagnets from Faraday and Kerr measurements
M. -H. Kim, G. Acbas, M. -H. Yang +8
We present measurement and analysis techniques that allow the complete complex magneto-conductivity tensor to be determined from mid-infrared (11-1.6 micron; 100-800 meV) measureme…
Non-Fermi liquid behavior near the ferromagnetic quantum critical point in the series Ca(x)Sr(1-x)RuO(3)
P. Khalifah, I. Ohkubo, H. Christen +1
A series of epitaxial films were grown across the solid solution Ca(x)Sr(1-x)RuO(3) in order to pinpoint the ferromagnetic to paramagnetic quantum phase transition in this system a…
