Local probes, such as μSR and NMR, spectroscopy are sensitive microscopic probes to
identify spin-liquid phases via the absence or presence of static magnetic moments and the
presence of enhanced low energy spin dynamics. These probes allow us to detect competing
magnetic ordered phases even in the absence of long range coherence of the magnetic order.
They are sensitive to determine the low energy-density of states of magnetic excitations. In
recent years we have used these probes to understand correlated magnetism: from frustration
to topology in different kinds materials which has different lattice geometry, such as the ideal
triangular lattice, the kagome lattice etc. In this presentation, I will discuss our recent progress
in this field by means of local probe studies by selectively identifying a few representative
compounds namely Fe-Kagome, NaYbS2, Na2IrO3 and RuBr3. I will discuss the importance of
these compounds and its relevance to frustration and topology. |
