  The time-dependent spin current mediated spin transfer torque behaviour has
been investigated via scattering formalism within density functional theory
framework supported by Green's function. Quantum magnetotransport
characteristics have been revealed in a model semiconducting
MoS$_2$/phosphorene van der Waals heterostructure. The dynamics of spin current
channelized heterolayer transport has been studied with rotational variation in
magnetization angle. It is observed that the time-dependent spin transport
torque remains invariant irrespective of magnetization angle direction. The
polarized spin-current is persistent with the external magnetic field for
potential applicability towards spintronics.
