  • Effect of Next Nearest Neighbor Interaction on Thermodynamic Properties of Ultrathin Magnetic Films

    • Authors: Nguyen, Tu Niem; Bach, Thanh Cong (2019)

  • This work studies on the thermodynamic properties of the ultra-thin magnetic films within the framework of a transverse Ising model. Equations for free energy, entropy and specific heat of spin system are obtained by using the mean field approximation. We also analyze the effect of the next nearest neighbor interaction on critical temperature, layer magnetization and specific heat of the thin films.

  • Orderedisorder phase transitions in thin films described by transverse Ising model

    • Authors: Nguyen, Tu Niem; Bach, Huong Giang; Bach, Thanh Cong (2016)

  • The order-disorder phase transition in thin films at finite temperature and zero temperature (quantum phase transition) is discussed within the transverse Ising model using molecular field approximation. Experimentally, it is shown that the Curie temperature TC of perovskite PbTiO3 ultra-thin film decreases with decreasing film thickness. We obtain an equation for TC of thin film in external magnetic and transverse fields. Our equation explains well for the case of strong transverse strain field this behaviour.
