X-ray magnetic circular dichroism study of Re 5d magnetism in Sr2CrReO6

P. Majewski, S. Gepraegs, O. Sanganas +5

We have measured Re 5d spin and orbital magnetic moments in the ferrimagnetic double perovskite Sr2CrReO6 by X-ray magnetic circular dichroism at the L_{2,3} edges. In fair agreeme…

Spin-glass-like behavior of Ge:Mn

C. Jaeger, C. Bihler, T. Vallaitis +4

We present a detailed study of the magnetic properties of low-temperature-molecular-beam-epitaxy grown Ge:Mn dilute magnetic semiconductor films. We find strong indications for a f…

Study of Magnetic Properties of A_2B^'NbO_6 (A=Ba,Sr, (BaSr): and B^'=Fe and Mn) double perovskites

N. Rama, J. B. Philipp, M. Opel +4

We have studied the magnetic properties of Ba_2FeNbO_6 and Ba_2MnNbO_6. it is seen that Ba_2FeNbO_6 is an antiferromagnet with a weak ferromagnetic behaviour at 5K while Ba_2MnNbO_…

Voltage controlled inversion of magnetic anisotropy in a ferromagnetic thin film at room temperature

M. Weiler, A. Brandlmaier, S. Gepraegs +7

The control of magnetic properties by means of an electric field is an important aspect in magnetism and magnetoelectronics. We here utilize magnetoelastic coupling in ferromagneti…

Magnetic moments of W 5d in Ca2CrWO6 and Sr2CrWO6 double perovskites

P. Majewski, S. Gepraegs, A. Boger +9

We have investigated the magnetic moment of the W ion in the ferrimagnetic double perovskites Sr2CrWO6 and Ca2CrWO6 by X-ray magnetic circular dichroism (XMCD) at the W L(2,3) edge…

Carrier relaxation, pseudogap, and superconducting gap in high-Tc cuprates: A Raman scattering study

M. Opel, R. Nemetschek, C. Hoffmann +9

We describe results of electronic Raman-scattering experiments in differently doped single crystals of Y-123 and Bi-2212. The comparison of AF insulating and metallic samples sugge…
