abstract

• The electron transport through a single molecule magnet transistor in the presence of a local transverse magnetic field and ac-driven gate voltage has been considered. The conductance has been calculated as a function of the electron energy and transverse magnetic field by using the Floquet and Landauer formalism. It is shown that the time periodic potential causes zero transmission resonances that oscillate as a function of the transverse magnetic field due to the Berry phase interference associated with two quantum tunneling paths. It has been found that these Berry phase oscillations can be detected in the conductance as a function of the transverse magnetic field for an incoming electron with a specific energy. © 2019 WILEY-VCH Verlag GmbH %26 Co.
