Experimental studies of metals with quasi-1D electronic structure /////// Effective confinement of dimensional degrees of freedom in solid matter is well known for its crucial role in various emergent phenomena of solid state physics such as high-temperature superconductivity, novel magnetic states based on dimensional frustration and various others. Materials with effectively quasi-one-dimensional electronic structures are prone to alter their crystal structure via a so-called charge density wave (CDW) instability. Among such CDW systems, rare-earth nickel dicarbides represent a unique class of materials allowing to study a systematic evolution of charge density wave states, which due to competing symmetries display distinctly different features. These CDW states compete with each other and further interact in distinctly different manners with other competing order parameters such as superconductivity and rare-earth magnetism. In the present talk, we report on experimental studies of the physics of rare-earth nickel dicarbides. Our experimental work comprises single crystal growth and investigations of crystallographic, magnetic and electronic properties with broad range of experimental techniques such as XRD (single crystal and powder techniques), thermal expansion, specific heat and a variety of electro-, thermo-, and magneto-transport measurements. Experimental studies are supplemented by DFT electronic structure studies revealing interrelations between features of CDW order, anisotropy of electronic transport properties and Fermi surface topology. Our results sched light on a variety of novel aspects of quasi-one-dimensional metals with competing order parameters.
