The phase diagrams and magnetizations of transverse Ising nanowires with simple core-shell structure are investigated by the use of the effective field theory with correlations. Many unconventional phenomena have been found for them, when the transverse field at the surface shell (ΩS) is selected as a finite value (ΩS = Ω) and the transverse field in the core (ΩC) is fixed at ΩC = 0.0, such as the reentrant phenomena, the appearance of a compensation point, and the unexpected behaviors of a critical transverse field (Ω = ΩC) at which the transition temperature reduces to zero.
