In this thesis, after introducing some theoretical aspects of Mott insulators, pure single crystals of the Mott insulator Ca2RuO4 was investigated from an experimental point of view. The surprisingly low current density ...

Superconductivity under pressure was recently discovered in two transition metal pnictides belonging to the Pnma space group, namely CrAs [1, 2] and MnP [3], in the vicinity of a magnetic phase, respectively at the ...

Transition Metal Oxides (TMOs) show a wealth of intriguing properties which are governed by the interplay of charge, spin, and orbital degrees of freedom. Moreover, the comprehension of the features of strongly ...

The present work focuses on case studies conducted from 2014 to 2016 in Secondary Schools in Campania where new teaching methodologies for teaching - Physical Learning have been experimented. Of these methodologies, ...

The actual surveys highlight that teaching scientific disciplines it gives often-inadequate results, in Italy particularly, and it emerges that, in general, the educational aspects of the teaching of the Physics are not ...

In the scientific community there is a great interest to explore new superconducting materials suitable for high field applications in order to meet the needs of industrial claims. In this framework, newly discovered ...

This work is focused on two helimagnetic materials: Ba2CuGe2O7 and Cu3Nb2O8. Recent studies report a number of interesting anisotropic proper- ties [1, 2, 3]. Ba2CuGe2O7 melilite oxide shows a complex magnetic behaviour, ...

In questa Tesi di Dottorato, io e il mio supervisor, il Prof. Roberto De Luca, abbiamo analizzato alcuni particolari dispositivi superconduttori, le giunzioni Josephson e gli SQUIDs (Superconducting Quantum Interference ...

Type II superconducting materials are technologically interesting since they are characterized by the existence of a superconducting phase even after the penetration of the magnetic field inside them. In fact, while type ...

The transition metal oxides are emerging as the natural playground where the intriguing effects induced by electron correlations can be addressed. Since the s electron of the transition metals are transferred to the ...
