On the possibility of magnetic ordering (TC(N)) induced by a surface exchange interaction in an Ising nanoparticle with TC(N) > TC(B), where TC(B) is a transition temperature in the corresponding bulk system

•Two Ising nanoparticles are investigated.•Their corresponding bulks are investigated.•The phase diagrams and magnetizations are discussed by using the EFT.•The possibility of Tc(N) (nanoparticle) > Tc(B) (bulk) is discussed. The phase transitions of two nanoparticles and their corresponding bulk...
