Nitrogen based magnetic semiconductors (2006)
Elfimov, I. S., Rusydi, A., Csiszar, S. I., Hu, Z., Hsieh, H. H., ...
We describe a possible pathway to new magnetic materials with no conventional magnetic elements present. The substitution of Nitrogen for Oxygen in simple non magnetic oxides leads to holes in N 2$p$...
Controlling orbital moment and spin orientation in CoO layers by strain (2005)
Csiszar, S. I., Haverkort, M. W., Hu, Z., Tanaka, A., Hsieh, H. H., ...
We have observed that CoO films grown on different substrates show dramatic differences in their magnetic properties. Using polarization dependent x-ray absorption spectroscopy at the Co L$_{2,3}$...
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...
Magnetic versus crystal field linear dichroism in NiO thin films (2003)
Haverkort, M. W., Csiszar, S. I., Hu, Z., Altieri, S., Tanaka, A., Hsieh, H. H., ...
We have detected strong dichroism in the Ni $L_{2,3}$ x-ray absorption spectra of monolayer NiO films. The dichroic signal appears to be very similar to the magnetic linear dichroism observed for...
Direct observation of electron doping in La0.7Ce0.3MnO3 using x-ray absorption spectroscopy (2003)
Mitra,C., Hu,Z., Raychaudhuri,P., Wirth,S., Csiszar,S. I., Hsieh,H. H., ...
Direct observation of electron doping in La0.7Ce0.3MnO3 using x-ray absorption spectroscopy (2003)
Mitra, C., Hu, Z., Raychaudhuri, P., Wirth, S., Csiszar, S. I., Hsieh, H. H., ...
Direct observation of electron doping in La0.7Ce0.3MnO3 using x-ray absorption spectroscopy (2002)
Mitra, C., Hu, Z., Raychaudhuri, P., Wirth, S., Csiszar, S. I., Hsieh, H. H., ...
We report on a X-ray absorption spectroscopic (XAS) study on a thin film of La0.7Ce0.3MnO3, a manganite which was previously only speculated to be an electron doped system. The measurements clearly...
