Experimental determination of the orientation of tilted magnetic anisotropy by measuring Hall voltage
Hasan Piskin, Erdem Demirci, Mustafa Ozturk +1
The orientation of the tilted magnetic anisotropy has crucial importance in many spintronic devices. However, it is very challenging to determine it especially in very small struct…
Shapeable planar Hall sensor with a stable sensitivity under concave and convex bending
B. Özer, H. Pişkin, N. Akdoğan
A shapeable planar Hall sensor has been fabricated by lift-off a bilayer structure of NiFe(10 nm)/IrMn (8 nm) grown on a Kapton/PDMS substrate without using a buffer layer. The sen…
Interface induced manipulation of perpendicular exchange bias in Pt/Co/(Pt, Cr)/CoO thin films
N. Akdogan, A. Yagmur, M. Ozturk +3
Perpendicular exchange bias has been manipulated by changing ferromagnetic film thickness and spacer layer in Pt/Co/(Pt, Cr)/CoO thin films. The exchange bias characteristics, bloc…
Temperature-dependent exchange bias properties of polycrystalline PtxCo1-x/CoO bilayers
Erdem Demirci, Mustafa Öztürk, Ekrem Sınır +4
Temperature and PtCo composition dependence of exchange bias in PtxCo1-x/CoO bilayers is investigated. It is observed that exchange bias properties, blocking temperature and magnet…
Six-fold in-plane magnetic anisotropy in Co-implanted ZnO (0001)
Numan Akdogan, Bulat Rameev, Sumeyra Guler +5
Magnetic anisotropies of Co-implanted ZnO (0001) films grown on single-crystalline Al2O3 (11-20) substrates have been studied by ferromagnetic resonance (FMR) technique for differe…
Dose dependence of ferromagnetism in Co-implanted ZnO
Numan Akdogan, Hartmut Zabel, Alexei Nefedov +5
We have studied the structural, magnetic and electronic properties of Co-implanted ZnO (0001) films grown on Al2O3 (1120) substrates for different implantation doses and over a wid…
High temperature ferromagnetism in Co-implanted TiO2 rutile
Numan Akdogan, Alexei Nefedov, Hartmut Zabel +7
We report on structural, magnetic and electronic properties of Co-implanted TiO2 rutile single crystals for different implantation doses. Strong ferromagnetism at room temperature…
Intrinsic room temperature ferromagnetism in Co-implanted ZnO
Numan Akdogan, Alexei Nefedov, Kurt Westerholt +5
We report on the structural and magnetic properties of a cobalt-implanted ZnO film grown on a sapphire substrate. X-ray diffraction and transmission electron microscopy reveal the…
