  This study presents the largest mid-infrared spectral catalog of Herbig Ae/Be
stars to date, containing the Spitzer Infrared Spectrograph spectra of 126
stars. Based on the catalog analysis, two prominent infrared vibrational modes
of C\textsubscript{60} bands at 17.4 $\mu m$ and 18.9 $\mu m$ are detected in
the spectra of nine sources, while 7.0 $\mu m$ feature is identified in the
spectra of HD 319896. The spectral index analysis and the comparison of the
known sources with C\textsubscript{60} features indicated that there exist two
different types of emission classes among the sample of stars. The infrared
spectra of six Herbig Ae/Be stars in this study resemble that of reflection
nebulae, and their association with previously known reflection nebulae is
confirmed. In the case of three Herbig Ae/Be stars we report the tentative
evidence of C\textsubscript{60} emission features originating from the
circumstellar disk or nearby diffused emission region. The detection fraction
of C\textsubscript{60} in the total HAeBe star sample is $\sim$ 7\%, whereas
the detection fraction is 30\% for HAeBe stars associated with nebulosity. In
the catalog, C\textsubscript{60} is exclusively present in the circumstellar
regions of B type Herbig Ae/Be stars, with no evidence of its presence detected
in stars with later spectral types. The present study has increased the number
of young stellar objects and reflection nebulae detected with
C\textsubscript{60} multifold, which can help in understanding the excitation
and formation pathway of the species.
