The CePtSi_0.9Ge_0.1 unaligned Pt NMR spectrum shows a typical powder broadening pattern and is similar to the Si spectrum, but is much broader.

l         There is a peak at 23 KOe which was also seen in aligned H ^ c Pt spectrum.

l         The peak around 22.6 KOe is the ⁶³Cu signal from the copper coil.

l         The quadrature part is not minimized just like the one in Si spectrum. It also found that the phase gradually changed at different swept magnetic field, which is believed to be the reason to make the quadrature part not minimized.
