The spin phenomena, particularly the spin-polarized transport of electrons in metals and 
semiconductor paved wave for a new field, the spintronics (spin-electronics). The fundamental aspects of 
the spintronics is the investigation of spin-orbit interactions, spin exchange coupling and microscopic 
mechanisms such as long-range order in semiconductor systems, spin relaxation and spin dephasing in 
magnetic materials. The ultra-fast (nanosecond – femtoseconds) dynamics and other phenomena of the spin 
systems lead the development of various devices ranging from quantum bits (qbits), magnetic memories, 
high frequency (GHz, THz) signal generators, etc[1]. Recently the spin dynamics are investigated for the 
next generation computing hardware alternative to the current van Neumann computing architecture 
inspired from the brain-inspired physical phenomena[2]. Here, I will present about the fundamental 
properties of spin transport and dynamics and various spintronics devices that being developed on the 
neuromorphic, reservoir computing principles. I will discuss in detail about a spintronics oscillator device, 
the spin Hall oscillator and its capability of developing a novel hardware applicable to artificial neural 
networks[3,4].
