Probing structural and dynamic properties of MAPbCl3 hybrid perovskite using Mn2+ EPR

Michael Allan Hope, Yuxuan Zhang

Hybrid methylammonium (MA) lead halide perovskites have emerged as materials exhibiting excellent photovoltaic performance related to their rich structural and dynamic properties. Here, we use multifrequency (X-, Q-, and W-band) electron paramagnetic reson ...

Magnetic Properties of Surface Adsorbed Metal Adatoms and Dimers

Dante Philippe Sblendorio

This thesis investigates the magnetic properties of single atoms and dimers adsorbed on graphene and oxide decoupling layers supported by single crystal metal substrates, using scanning tunneling microscopy (STM) and spin-polarized scanning tunneling micro ...

Uniform water-mediated saturation transfer: A sensitivity-improved alternative to WaterLOGSY

Federico De Biasi

In the study of small molecule ligands and candidate macromolecular targets, water spins in long-lived association with macromolecules (proteins or nanoparticles) constitute a remarkable source of magneti-zation that can be exploited to reveal ligand-targe ...

Static and dynamic properties of non-collinear quantum antiferromagnets explored by neutron scattering

Luc Testa

This thesis is devoted to the investigation of static and dynamic properties of two different sets of quantum magnets with neutron scattering techniques and the help of linear spin wave theory. Both systems are copper-based with spin-1/2, which makes them ...

Electrochemical Overhauser dynamic nuclear polarization

Jean-Philippe Ansermet, Christophe Roussel, Jonas Milani, Mika Antero Tamski

Nuclear Magnetic Resonance (NMR) spectroscopy suffers from low sensitivity due to the low nuclear spin polarization obtained within practically achievable external magnetic fields. Dynamic Nuclear Polarization (DNP) refers to techniques that increase the N ...

Generic phase diagram of spin relaxation in solids and the Loschmidt echo

Ferenc Simon

The spin relaxation time in solids is determined by several competing energy scales and processes, and distinct methods are called for to analyze the various regimes. We present a stochastic model for the spin dynamics in solids which is equivalent to solv ...

AMER PHYSICAL SOC2020

The valley degree of freedom is intrinsic to spin qubits in Si/SiGe quantum dots. It has been viewed alternately as a hazard, especially when the lowest valley-orbit splitting is small compared to the thermal energy, or as an asset, most prominently in pro ...

The time-window for processing electron spin information (spintronics) in solid-state quantum electronic devices is determined by the spin-lattice and spin-spin relaxation times of electrons. Minimizing the effects of spin-orbit coupling and the local magn ...

Anisotropic Elliott-Yafet theory and application to KC8 potassium intercalated graphite

László Forró, Bálint Náfrádi, Péter Szirmai, Ferenc Simon, Bence Gábor Márkus

We report electron spin resonance (ESR) measurements on stage-I potassium intercalated graphite (KC8). Angular dependent measurements show that the spin-lattice relaxation time is longer when the magnetic field is perpendicular to the graphene layer as com ...

Long-lived nuclear spin states of magnetically equivalent protons by means of dissolution dynamic nuclear polarization

Daniele Mammoli

Nuclear Magnetic Resonance (NMR) is one of the most versatile techniques since it enables the characterization of solid, liquid and gaseous systems in a plethora of in-vitro and in-vivo experiments. Despite its multidisciplinary scope, it still suffers fro ...
