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…
Multiple phases in sputtered Cr2CoGa films
Manuel P. Geisler, Markus Meinert, Jan Schmalhorst +2
By magnetron co-sputtering, thin films of a nominal Cr2CoGa compound were deposited on MgO and MgAl2O4. To achieve crystallisation in the inverse Heusler structure, different heat…
Electronic structure and optical band gap determination of NiFe2O4
Markus Meinert, Günter Reiss
In a theoretical study we investigate the electronic structure and the band gap of the inverse spinel ferrite NiFe2O4. The experimental optical absorption spectrum is accurately re…
High TMR ratio in Co2FeSi and Fe2CoSi based magnetic tunnel junctions
Christian Sterwerf, Markus Meinert, Jan-Michael Schmalhorst +1
Magnetic tunnel junctions with Fe1+xCo2-xSi (0 < x < 1) electrodes and MgO barrier were prepared on MgO substrates by magnetron co-sputtering. Maximum tunnel magnetoresistance (TMR…
Phase separation in Fe2CrSi thin films
Markus Meinert, Torsten Hübner, Jan Schmalhorst +2
Thin films of a nominal Fe2CrSi alloy have been deposited by magnetron co-sputtering with various heat treatments on MgO and MgAl2O4 substrates. After heat treatment, the films wer…
Phase stability of chromium based compensated ferrimagnets with inverse Heusler structure
Markus Meinert, Manuel Geisler
Chromium based inverse Heusler compounds of the type Cr2YZ (Y=Co, Fe; Z=Al, Ga, In, Si, Ge, Sn) have been proposed as fully compensated half-metallic ferrimagnets. Such materials a…
