Magnetic anisotropy of La0.7Sr0.3MnO3 nanopowders
I. Radelytskyi, P. Dluzewski, V. Dyakonov +4
The magnetic anisotropy of La0.7Sr0.3MnO3 nanopowders was measured as a function of temperature by the modified singular point detection technique. In this method singularities ind…
Spin-current mediated exchange coupling in MgO-based magnetic tunnel junctions
L. Gladczuk, P. Dluzewski, K. Lasek +4
Heterostructures composed of ferromagnetic layers that are mutually interacting through a nonmagnetic spacer are at the core of magnetic sensor and memory devices. In the present s…
Homogenous and heterogeneous magnetism in (Zn,Co)O
M. Sawicki, E. Guziewicz, M. I. Lukasiewicz +21
A series of (ZnO)m(CoO)n digital alloys and superlattices grown by atomic layer deposition has been investigated by a range of experimental methods. The data provide evidences that…
Magnetic Phase Diagram of Mn3+xSn1-x Epitaxial Thin Films: Extending the Anomalous Hall Effect to Low Temperatures via Intrinsic Alloying
