Sažetak
Rapid technological development affects every part of human action, from energy and communications to health and household. Stepwise jumps in this continous growth happen when new concepts or new states of matter are discovered. A large playground to discover novel phases of matter can be found in strongly correlated electron systems (SCES), comprising high-temperature superconductivity, quantum magnetism, heavy fermion systems, quantum Hall effect, etc. The discovery of such new phases is the forefront of modern condensed matter research. In SCES, competing interactions, collective phenomena, and quantum criticality ensure an enormous wealth of orderings and extraordinary complex phase diagrams, where the control parameter can be temperature, magnetic field, pressure or doping. Theoretical investigations predict the existence of novel even more exotic phases with yet unexplored properties. An interesting example are nematic phases predicted in frustrated spin systems or in high temperature superconductors. They are experimentally hard to detect since they break rotational, but not translational symmetry. To detect such phases one should apply a combination of several experimental methods, and some of them are rather unconventional. Here we show how a combination of nuclear magnetic relaxation, differential heat capacity and nonlinear conductivity may help to discover and characterize such nematic phases. We will also present some other experimental methods that are available in the Laboratory for solid state NMR and high frequency measurements at our Department.
