      abstract     = {We have investigated low energy nuclear spin excitations in
                      the strongly correlated electron compound HoCrO3. Weobserve
                      clear inelastic peaks at E D 22:18 0:04 eV in both energy
                      loss and gain sides. The energy of the inelasticpeaks
                      remains constant in the temperature range 1.5–40 K at
                      which they are observed. The intensity of the inelasticpeak
                      increases at first with increasing temperature and then
                      decreases at higher temperatures. The temperaturedependence
                      of the energy and intensity of the inelastic peaks is very
                      unusual compared to that observed in other Nd, Co,V and also
                      simple Ho compounds. Huge quasielastic scattering appears at
                      higher temperatures presumably due to thefluctuating
                      electronic moments of the Ho ions that get increasingly
                      disordered at higher temperatures. The strongquasielastic
                      scattering may also originate in the first Ho crystal-field
                      excitations at about 1.5 meV.},
