- Gina Rose Tongco is a Bachelor of Science graduate major in Physics at the National Institute of Physics (NIP), University of the Philippines, Diliman. She made her undergraduate thesis at the Structure and Dynamics (SanD) Group under the supervision of Dr. Cristine Villagonzalo. Her research on low dimensional magnetic systems has modeled a nonintuitive phenomenon regarding the occurrence of ferromagnetism at low temperatures. She is currently a junior software engineer at Accenture. She plans to pursue masters degree in physics at NIP on 2007.

Schematic of the magnetic ring
The effects of a long-range interaction in a one-dimensional (1D) magnetic ring is studied. In this work, the Monte Carlo method is employed to obtain the equilibrium state of a modified quasi-1D Ising model having a dipolar interaction in a ring geometry. At low temperatures (T), the behavior of the magnetization (M) as a function of T is shown to depend on the strength of the dipolar interaction (G). For a ring consisting of 10 spins, ferromagnetic states occur in the ground state (T = 0) for a small value of G. Antiferromagnetic states are favored when G is large even at a finite temperature. The magnetization saturates at high T. Also, an effective lowering of the total energy is achieved when smaller values of G approach zero and when large value of G is increased further. Similar effects are observed for rings having a larger number of spins.
