Query: Magnetic Skyrmions in Condensed Matter Physics   Skyrmions were originally introduced in Particle Physics as a possible
mechanism to explain the stability of particles. Lately the concept has been
applied in Condensed Matter Physics to describe the newly discovered
topologically protected magnetic configurations called the magnetic Skyrmions.
This elementary review introduces the concept at a level suitable for beginning
students of Physics.
