Strong electron correlations underlie a plethora of electronic and magnetic components and devices and are often used to identify and probe novel ground states in quantum materials. Herein we report a magnetic phase crossover in EuMn2P2, an insulator

NaTiSi2O6 is an exemplary compound, showing an orbital assisted spin-Peierls phase transition at Tc = 210 K. We present the results of 29Si and 23Na NMR measurements of NaTiSi2O6. The use of magic angle spinning techniques unambiguously shows that on

Classical and quantum phase transitions (QPTs), with their accompanying concepts of criticality and universality, are a cornerstone of statistical thermodynamics. An exemplary controlled QPT is the field-induced magnetic ordering of a gapped quantum

The magnetic structure of the antiferromagnetic square cupola compound Ba(TiO)Cu$_4$(PO$_4$)$_4$ with the tetragonal structure is studied with 31P nuclear magnetic resonance techniques. The magnetic hyperfine shift K shows a clear splitting at the N\

We present a structural analysis of the substituted system (Ba$_{1-x}$Sr$_{x}$)CuSi$_{2}$O$_{6}$, which reveals a stable tetragonal crystal structure down to 1.5 K. We explore the structural details with lowtemperature neutron and synchrotron powder
