While Y(Mn1-xAlx)2 (x<0.02) is seen as a system of AF coupled local Mn moments (T<110K), alloys with 0.02<x<0.3 show characteristics of a topologically frustrated spin glass-like material. High pressure neutron diffraction, however, suggests 4.5kB inhibits Tg leaving a paramagnetic ground state and a lattice parameter close to that of AF material (x<0.02). Unlike alloys with x<0.02, however, no AF transition is observed and weak magnetic reflections are suppressed. Recent LF-uSR (LF=110G) high pressure studies (ARGUS) have allowed the mechanisms driving frustration to be probed further on a local level. A pressure dependent change in the relaxation function, Gz(t), suggests external pressure suppresses the frustrated ground state. However, to confirm this we now aim to show that the observed changes in Gz(t) are wholly pressure dependent and not influenced by the application of LF=110G
