Phase diagrams in an Ising nanotube (or nanowire) with a diluted surface; Effects of interlayer coupling at the surface

► Phase diagrams and total magnetizations are examined for nanotube and nanowire. ► The effects of surface dilution on them are examined by using the EFT. ► Unexpected behaviors of Tc curve are obtained for the two systems. ► The possibility of two compensation points is obtained for nanowire.
