  Geometrically frustrated materials, such as spin ice or kagome lattice, are
known to exhibit exotic Hall effect phenomena due to spin chirality. We explore
Hall effect mechanism in an artificial honeycomb spin ice of Nd--Sn element
using Hall probe and polarized neutron reflectivity measurements. In an
interesting observation, a strong enhancement in Hall signal at relatively
higher temperature of $T$ $\sim$ 20 K is detected. The effect is attributed to
the planar Hall effect due to magnetic moment configuration in spin ice state
in low field application. In the antiferromagnetic state of neodymium at low
temperature, applied field induced coupling between atomic Nd moments and
conduction electrons in underlying lattice causes distinct increment in Hall
resistivity at very modest field of $H$ $\sim$ 0.015 T. The experimental
findings suggest the development of a new research vista to study the planar
and the field induced Hall effects in artificial spin ice.
