  One of the main challenges in the field of thermal radiation is to actively
control the near-field radiative heat transfer (NFRHT) between closely spaced
bodies. In this context, the use of an external magnetic field has emerged as a
very attractive possibility and a plethora of physical phenomena have been put
forward in the last few years. Here, we predict some additional
magnetic-field-induced phenomena that can take place in the context of NFRHT
between planar layered structures containing magneto-optical (MO) materials
(mainly doped semiconductors like InSb). In particular, we predict the
possibility of increasing the NFRHT upon applying an external magnetic field in
an asymmetric structure consisting of two infinite plates made of InSb and Au.
We also study the impact of a magnetic field in the NFRHT between structures
containing MO thin films and show that the effect is more drastic than in their
bulk counterparts. Finally, we systematically investigate the anisotropic
thermal magnetoresistance, i.e., the dependence of the radiative heat
conductance on the orientation of an external magnetic field, in the case of
two infinite plates made of InSb and show that one can strongly modulate the
NFRHT by simply changing the orientation of the magnetic field. All the
phenomena predicted in this work can be experimentally tested with existent
technology and provide a new insight into the topic of active control of NFRHT.
