 Three-dimensional frustrated magnets have recently come into limelight as 
promising candidates to host the much sought after quantum spin liquid phase. 
Recent experiments on pyrochlore, hyperkagome, and diamond lattice compounds 
have revealed the presence of tremendously interesting and intriguing 
low-energy physics. Using the recently developed pseudo-fermion functional 
renormalization group (PFFRG) method which efficiently handles 3D spin 
systems, we address the low-energy physics of different spin liquid candidate 
materials in 3D which have been the subject of recent experimental 
investigation. This includes an extraordinarily rare realization of a S=1/2 
Molybdate pyrochlore (Lu2Mo2O5N2) and the spiral spin liquid phase in the 
S=5/2 diamond lattice Mn-Thiospinel (MnSc2S4). The spin susceptibility 
profiles obtained within PFFRG are shown to be in excellent agreement with 
available neutron scattering data, which displays fascinating features, such 
as the presence of cogwheels, boomerangs, and bow-ties.
