Fast, Broad-Band Magnetic Resonance Spectroscopy with Diamond Widefield Relaxometry

We present an alternative to conventional Electron the use of bulky magnets and magnetron equipment, we use the photoluminescence of an ensemble of Nitrogen-Vacancy centers at the surface of a diamond. Monitoring their relaxation time (or T1), we detected ...

Combined synchrotron x-ray diffraction and NV diamond magnetic microscopy measurements at high pressure

Mayeul Sylvain Chipaux, Charles Michel Henri Pépin, Margarita Lesik Gaussens

We report the possibility to simultaneously perform wide-field nitrogen-vacancy (NV) diamond magnetic microscopy and synchrotron x-ray diffraction measurements at high pressure. NV color centers are created on the culet of a diamond anvil which is integrat ...

Magnetic and Magnetoelectric Measurements on Ba2CoGe2O7

Thanh Phong Kevin Lê

Multiferroic materials show, in a single phase, at least two ferroic properties. The latter are are (anti-)ferroelectricity, (anti-)ferromagnetism or (anti-)ferroelasticity. Interesting applications can use the properties of multiferroics, especially with ...

Interfacial properties of LaMnO3/LaNiO3 superlattices grown along (001) and (111) orientations

Harald Brune, Stefano Rusponi, Jan Gui-Hyon Dreiser

We have employed x-ray absorption spectroscopy and x-ray magnetic circular dichroism (XMCD) at the Ni andMn L-3,L-2 edges in LaMnO3/LaNiO3 superlattices grown along (001) and (111) orientations. Our results show a significant XMCD signal and thus the prese ...

Effect of Heat Current on Magnetization Dynamics in Magnetic Insulators and Nanostructures

Francesco Antonio Vetrò

The term "spin caloritronics" defines a novel branch of spintronics that focuses on the interplay between electron spins with heat currents. In the frame of this research area, this thesis is aimed at investigating the effect of a heat current on magnetiza ...
