Ising magnetism and ferroelectricity in Ca$_3$CoMnO$_6$ (2008)
Wu, Hua, Burnus, T., Hu, Z., Martin, C., Maignan, A., Cezar, J. C., ...
The origin of both the Ising chain magnetism and ferroelectricity in Ca$_3$CoMnO$_6$ is studied by $ab$ $initio$ electronic structure calculations and x-ray absorption spectroscopy. We find that...
X-ray absorption and x-ray magnetic dichroism study on Ca3CoRhO6 and Ca3FeRhO6 (2008)
Burnus, T., Hu, Z., Wu, Hua, Cezar, J. C., Niitaka, S., Takagi, H., ...
Using x-ray absorption spectroscopy at the Rh-L_2,3, Co-L_2,3, and Fe-L_2,3 edges, we find a valence state of Co^2+/Rh^4+ in Ca3CoRhO6 and of Fe^3+/Rh^3+ in Ca3FeRhO6. X-ray magnetic circular...
Indirect electric field doping of the CuO2 planes of the cuprate NdBa2Cu3O7 superconductor (2008)
Salluzzo, M., Ghiringhelli, G., Cezar, J. C., Brookes, N. B., De Luca, G. M., Fracassi, F., ...
The mechanism of field-effect doping in the "123" high critical temperature superconductors (HTS) has been investigated by x-ray absorption spectroscopy in the presence of an electric field. We...
Burnus, T., Hu, Z., Haverkort, M. W., Cezar, J. C., Flahaut, D., Hardy, V., ...
We have investigated the valence, spin, and orbital state of the Co ions in the one-dimensional cobaltate Ca3Co2O6 using x-ray absorption and x-ray magnetic circular dichroism at the Co-L2,3 edges....
The spin state transition in LaCoO$_{3}$; revising a revision (2006)
Haverkort, M. W., Hu, Z., Cezar, J. C., Burnus, T., Hartmann, H., Reuther, M., ...
Using soft x-ray absorption spectroscopy and magnetic circular dichroism at the Co-$L_{2,3}$ edge we reveal that the spin state transition in LaCoO$_{3}$ can be well described by a low-spin ground...
Magnetism at the interface between ferromagnetic and superconducting oxides (2006)
Chakhalian, J., Freeland, J. W., Srajer, G., Strempfer, J., Khaliullin, G., Cezar, J. C., ...
Aligning spins in antiferromagnetic films using antiferromagnets (2005)
Csiszar, S. I., Haverkort, M. W., Burnus, T., Hu, Z., Tanaka, A., Hsieh, H. H., ...
We have explored the possibility to orient spins in antiferromagnetic thin films with low magnetocrystalline anisotropy via the exchange coupling to adjacent antiferromagnetic films with high...
