Microscopic Magnetism of A(TiO)Cu4(PO4)4 (A = Ba, Pb, Sr): 31P and 63,65Cu NMR Study

Riho Rästa, Ivo Heinmaa, Joosep Link +5

We report a comprehensive NMR study of the chiral square-cupola antiferromagnet Pb(TiO)Cu${}_4$(PO${}_4$)${}_4$ and compare its microscopic hyperfine and local-field parameters with the…
