Dimensional reduction by singlet blockade in the distorted kagome magnet YCa${}_3$(CrO)${}_3$(BO${}_3$)${}_4$

Umashankar Jena, Satish Kumar, Harald O. Jeschke +3

The distorted kagome borate YCa${}_3$(CrO)${}_3$(BO${}_3$)${}_4$ has a Curie-Weiss temperature of -140 K and shows no magnetic order down to $65$ mK. We determine its Heisenberg Hamiltonia…
