Physical characteristics and cation distribution of NiFe2O4 thin films with high resistivity prepared by reactive co-sputtering
Christoph Klewe, Markus Meinert, Alexander Boehnke +6
We fabricated NiFe2O thin films on MgAl2O4 (001) substrates by reactive dc magnetron co-sputtering in a pure oxygen atmosphere at different substrate temperatures. The film propert…
Electronic Structure of Magnetic Semiconductor CdCr_2Te_4: A Possible Spin-Dependent Symmetry Filter
Hunter Sims, Karthik Ramasamy, William H. Butler +1
We present a theoretical investigation of the electronic and magnetic structure of spinel CdCr_2Te_4 using density functional theory, its extensions via onsite Hubbard U interactio…
Epitaxial Growth of Spinel Cobalt Ferrite Films on MgAlO Substrates by Direct Liquid Injection Chemical Vapor Deposition
Liming Shen, Matthias Althammer, Neha Pachauri +5
The direct liquid injection chemical vapor deposition (DLI-CVD) technique has been used for the growth of cobalt ferrite (CFO) films on (100)-oriented MgAlO (MAO) substrate…
Quantitative study of the spin Hall magnetoresistance in ferromagnetic insulator/normal metal hybrids
Matthias Althammer, Sibylle Meyer, Hiroyasu Nakayama +18
We experimentally investigate and quantitatively analyze the spin Hall magnetoresistance effect in ferromagnetic insulator/platinum and ferromagnetic insulator/nonferromagnetic met…
Thermally driven spin and charge currents in thin NiFe2O4/Pt films
Daniel Meier, Timo Kuschel, Liming Shen +6
We present results on the longitudinal spin Seebeck effect (LSSE) shown by semiconducting ferrimagnetic NiFe2O4/Pt films from room temperature down to 50K base temperature. To the…
