abstract = {Blazars are a class of active galactic nuclei (AGN) where
the relativistic jet is pointed towards the observer. They
are powerful sources of non-thermal radiation from radio to
Very high energy(VHE) gamma-rays. Flat Spectrum Radio
Quasars (FSRQs) are a subclass of blazars where there are
broad absorption or emission lines present in the optical
spectra.The observed properties of FSRQs are strongly
affected by the magnetic field in the accretion disk which
changes the UV emission of Broad Line Region (BLR) and
infrared emission from the Dusty Torus.While many (774 as
reported in 4FGL-DR2 catalogue) FSRQs have been detected at
high energies(E>100 MeV), only a few (9 as of now) could be
detected at very-high energies (> 100 GeV).In this work, we
present observations of nine FSRQs performed by MAGIC
between 2008 and 2020 with a total observation time being
174 hours. For two of the sources, CTA102 and B2 2234+28A,
we include observations from the Fermi-LAT, Swift-UVOT,
Swift-XRT and KVA (Kungliga Vetenskapsakademien). The
multi-wavelength spectra for these sources show hints of
absorption.We also modelled the broadband emission of the
sources to look for signatures of absorption of VHE
gamma-ray emission in the BLR region.},
