Abstract
The magnetic properties (phase diagrams and magnetizations) of a transverse Ising nanotube with double (surface and core) walls are investigated for the two cases, using the effective field theory with correlations. The first case is that the transverse field ΩS at the surface wall is selected as a finite value and the transverse field ΩC in the core wall is fixed at ΩC = 0.0. The second case is that ΩS = 0.0 and the value of ΩC is changed. A number of unconventional phenomena have been found for them, such as the reentrant phenomena and the existence of a compensation point, depending on the selections of the two transverse fields as well as the finite size effects.
