N2 - Pt (111) hexagonal surface with tripod geometry constructed from four Pt atoms is investigated by first principle calculation. Interestingly, appreciable spin magnetic moment of 0.11 μB per Pt tripod atom and 0.9 μB per unit cell is observed without application of external electric field (EF). Further, the magnetic moment per Pt atom and/or unit cell can be tuned using EF of ±0.5 V/Å. Negative EF enhances the spin magnetic moment of tripod Pt atom and unit cell up to 0.137 μB and 1.29 μB, respectively. Positive EF reduces the spin magnetic moment of tripod Pt atom and unit cell down to 0.087 μB and 0.45 μB, respectively.
