Data used for "Microscopic Origin of Reduced Magnetic Order in a Metallic Host". The study was conducted on a well-characterised HoInCu4 single crystal with m = 630 mg with a horizontal (H, K, 0)-scattering plane. The diffraction studies were performed on the thermal and cold diffractometers ZEBRA and DMC at the Paul Scherrer Institut (PSI), Switzerland . On ZEBRA we used an incoming neutron wavelength of λ = 1.383 ˚A. The sample was cooled to temperatures below T = 0.1 K employing a cryostat with dilution insert. Reciprocal space maps were taken with sample rotation steps of 0.125 degree, and recorded with a position sensitive area detector. The background was measured in two datasets at T = 50 and 100 K, which were combined for the data analysis. The background-subtracted diffuse neutron scattering signal was analyzed with the Spinteract software package. An incoming wavelength λ = 4.5189 ˚A was used for the experiments on DMC, using either dilution or 3He inserts. The zero-field data of these two experiments were combined by accounting for intensity differences and systematic temperature shifts through overlapping data points. The field dependence of the magnetic signal was studied in a vertical 10 T-cyromagnet at fields from µ0H = 0 to 5 T with H||[0, 0, 1]. In all experiments at DMC, the background was determined at T = 50 K. The inelastic neutron scattering experiment was performed on the multiplexing spectrometer CAMEA at PSI using a dilution insert in a vertical 11 T-cryomagnet to reach a base temperature of T = 40 mK. Excitation spectra were recorded with one degree sample rotation steps with energy transfers E = 0 - 7 meV. We used incident energies Ei = 3.38 and 4.04 meV yielding an elastic resolution of 100 µeV full width at half maximum (FWHM) to study the low-energy zero-field excitations (E < 0.9 meV) of the material. For these data a background was taken at µ0H = 10 T for which the region E < 0.9 meV did not contain any magnetic fluctuations. An Ei = 5 meV was used for the scans under magnetic field, resulting in a FWHM of 180 µeV and E < 2 meV.
